Control of Complex Systems
Control Theory & Design
- Structure Evolution and Control
- System of Systems
- Co-operative Control
- Robust Control Design
- Algebraic Control Theory and Design
- Nonlinear Systems
- Large Scale Systems
Control Theory and Design is a well-established area of research activity of the centre and is centred around the development structural methodologies based on algebraic, geometric and algebro-geometric methods on one hand and robust H-∞ methodologies. The central idea running through is the role of "system structure" in issues such as the analysis and design of control systems and the understanding of formation, evolution of system structure and resulting properties within the framework of the integrated systems design. The structural methodologies are complemented by the development of robust H-∞ optimisation methods for design and system model simplification. The term "system structure" is linked to system invariants and the basic topology of interconnections expressed in terms of graphs and structured models. The adopted philosophy is that "structure" defines the central features which determine the nature of resulting system properties and the system potential to achieve a number of objectives, and control design is then performed using optimization methods on structured control schemes. Current research is focused on the study of complex systems by examining design issues in "Integrated System Design" and "Systems of Systems" system paradigms.
Integrated Systems Design provides the motivation for the development of methodologies addressing problems in Structure Evolving Systems (SES). Research in the area of System of Systems (SoS) focuses on their classification and the characterization of the notion of "systems play" that is central to their characterization. Important area of complexity is linked to the large dimensionality of systems and applications considered are in the areas of power systems, process systems and transport. Issues considered relate to Large Scale System Decomposition, Structured Model Reduction, and Design of Decentralisation Structures.
Multi-Agent Systems & Intelligent Methods
Research in this area focuses in the areas of Multi-Agent Systems and Intelligent Methods. Current Research activities involve: Adaptive Dynamic Programming for Smart Energy Systems, Data Mining techniques for Transport and Market Forecasting, Machine Learning techniques for cyber security and 3D vision, Computational modeling in prediction and reward learning in people with ASD, Formalization of emergence in Systems of Systems and Multi-Agent Co-ordination and Communication
Network Theory
- Redesign of Passive Networks
- Supply chains control
The problem of redesigning systems by changing elements, topology, organization is a major challenge where systems and control theory have a major role to play. Network redesign is a process involving an evolution to system structure under different types of transformations. A special case considered here is the redesign of passive electric networks which aims to change the natural dynamics of the network (natural frequencies) by modification of the network. A control theoretic framework for addressing issues of systems redesign is examined here.
The work on Supply Chains aims to analyze dynamic phenomena arising in supply chain models, driven by stochastic inputs and examine the characterization of the "bullwhip effect" (demand amplification).
Application Domains
- Unstable Vehicle Dynamics
- Industrial Automation
- Power Systems
The fundamental work in the areas of Control and Engineering systems leads to the development of methodologies, concepts and tools which are used in the study of problems in specific applications areas which include Transport, Energy, Supply Chains and Industrial Automation. Research in such areas is linked to EU-funded projects. Specifically:
- The Control of unstable vehicle dynamics deals complex nonlinear dynamical systems such as rotorcrafts and high performance motorbikes. For helicopter, unstable behaviour involves the design of a high fidelity computer models enabling the study and understanding of existing pathological dynamics. In motorcycle dynamics we examine the development of mechanical steering compensators to improve the dynamic behaviour of high-performance motorcycles.
- Process Control has been a long-standing activity supported by a number of EU projects, where the development of control structures for large scale process systems has been an area of interest. Current work deals with the development of modelling, measurement and control for Powder Coating Manufacturing process within an EU project.
- Research in Power Systems deal with problems in Transmission and distribution networks, distributed generation, lightning, and embedded power systems using AI techniques and Artificial Neural Nets. Of special interest is the study of partitioning of systems (islanding methodologies) which is linked to the study of protection of power systems. Robust H-∞ methodologies are central to the development of model reduction techniques.

Wireless Networks
Wireless networks and related technology research focuses on Wireless Networks and deals with the development of networking technologies and protocols, which enable the high-speed data exchange users or modern wireless networks development. Research here is focused on the quality of service provision and involves control and optimisation of wireless communication networks in a wide range of wireless network systems, including local and metropolitan wireless networks. The research involves: Optimal scheduling, dynamic clustering: Cooperation and network self-organisation; Heterogeneous "4G" cellular networks, energy network optimisation; Wireless sensor Networks routing. Application of some of the optimisation solutions are found in energy networks.
Radar Systems and Signal Processing
Sophisticated drone technology is now available to everyone as it is becomes affordable and easy to deploy. Whilst this promotes a wide range of leisure and hobbyist activity it also heralds new weapons for terrorists and criminal organisations with possible threats to vital infrastructure. Security services have turned their attention to improving surveillance technology to track drone activity near or above sensitive areas but a problem exists with detecting slow moving very small objects hidden amongst noise and clutter with traditional radar technology. The centre is working with a Cambridge-based UK radar company, Aveillant Ltd, to enhance the signals processing functionality of a new concept radar that has the potential to identify and track all drones. This radar has unique characteristics in that it can survey in all directions at the same time for long periods and hence it possesses the potential to detect most drone activity even with high-levels ground clutter present.

Power Systems
The “Smart Grid” is becoming more complex due to the increased participation of consumers, and greater reliance on renewable resources. More specifically, distribution systems are no longer considered as supply points; they comprise of an increasing number of distributed generation; storage devices, e.g., electric vehicles; and combined heat & power. In this regard, to maintain the reliable system operation a hierarchical approach is required where at the higher level power system planning, and operation and management will be performed and at the lower level power electronic devices will be controlled. However, these tools need to be scalable from a computational and communication point of view to handle the increased complexity of the envisioned power system architecture. To this end, research needs to focus on the use of distributed management schemes that alleviate the computational burden rendering the proposed solutions scalable and implementable in large-scale complex power systems.
Energy storage in playing an increasingly important role in modern electrical energy system grids both national and micro. The applications of such storage range from timescales of milliseconds to years and therefore a range of characteristics are needed. For example with the displacement of a large centralised fossil fuelled power stations with renewables, the stabilising inertia is being removed from the system which is vital to keep the grid frequency and voltage stable. This must be replaced with fast reacting energy storage systems which buy time before other energy systems can come on stream which may take many seconds or even minutes. This service is currently being provided by Lithium-Ion batteries but more is needed. Although Lithium-Ion batteries fulfil this function very well they have limited life and recycling of the cell is still a major issue. An alternative is to use flywheels which, as a mechanical technologies, lasts decades. This can be paired with compressed air and pumped hydro to cover a longer duration of storage and potentially offer a lower cost and more sustainable solution. In microgrids currently powered by diesel generators, flywheels can offer a robust alternative to batteries to stabilise the system when solar voltaics are introduced to reduce operation of the diesel. The research at City on flywheels covers two areas, modelling of micro grids incorporating flywheels based on high fidelity models and research into flywheel rotor design. In particular, a laminated steel rotor has been developed which offers to substantially reduce costs of flywheel technology bringing it below the cost of Li-Ion batteries for high cycle applications.

Research projects & outputs
Recent grants (2008-present)
Control of Complex Systems
Project: IAPP GLOW, FP7-Research for SME-2013-1, "New weather-stable low gloss powder coatings based on bifunctional acrylic solid resins and nanoadditives",(2013-2017, City: €575,000); N Karcanias (Principal Investigator (PI)), G Halikias (Co-Investigator (CI)), E Milonidis (CI)
The project aims to develop novel, advanced polymer-based raw and composite materials as well as processing and production technologies, towards new families of powder coatings, i.e. one-shot matt powder coatings, responding at the same time to the industrial requirements for quality improvement at lower cost, production of environmentally friendly materials and shorter development cycles. The project will pursue the generation of multifunctional formulations, based on new bi-functional polymeric binders and new nanoadditives aiming to expand significantly, both in terms of type and final application. The industrial system that will manufacture the new paints requires upgrading of the existing process systems (two industrial partners). Our role is to undertake the challenges of industrial automation by providing expertise in process control, industrial systems, integration in upscalling of processes to the industrial production level. In addition to the technology tasks we deal with the training of our industrial partners by: identifying the specific research and training needs for the scaling up of Laboratory Processes an developing a "Technology Watch" System for the upscaling of the Laboratory results.
Project: CompETe, FP7-Research for SME-2013-1: "Composites Evaluation in aircraft industry through Triplex IR imaging system", (2013-2015, City: €374,400); N Karcanias (PI), G Halikias (CI), Project Coordination
The project aims to develop an advanced non-invasive imaging tool for qualitative and quantitative inspection of composites used primarily but not only in aircraft applications. This novel system will be using automated scanning via the use of a polyarticulated robotic arm equipped with sophisticated and innovative sensors operating in three infrared wavelengths (near, medium and long wave). Novel sensings system are used to acquire images during the non-destructive inspection of composites in the three infrared wavelengths. The automated tool will allow fast and prompt inspection of different composites components in the aerospace industry using Near Infrared Vision, Mid Wave IR Thermography, and Long Wave IR Thermography. The system will incorporate a novel image processing module combining and enhancing the individual inspection capabilities of the three imaging sensors and automatically recognising defects that may be undetectable otherwise. City's role is in the area of signal processing, pattern recognition and overall systems integration of the partial diagnostics tools. We are also acting as Project coordinators.
Engineering Systems
Project: EU: FRAMEWORK 6, Collective Research Project TESS: "Speciality Chemicals Manufacturing SMEs: Toolbox to support Environmental and Sustainable Systems", (2006-2009, City: €460,000). N. Karcanias, G. Halikias
The project aimed to enable European SME manufacturers of Specialty and Fine Chemicals to identify gaps in their current ability to deal with the transition into REACH-compliancy and associated migration to Sustainable Manufacturing. This will be achieved by carrying out background research, to empower them with the protocols, tools and manufacturing methodologies, currently beyond their economic and knowledge horizons, but essential for making this journey. City's involvement was in the area of developing methodology and a Toolbox for the systems, and economic appraisal of alternative chemical supply chains and thus enable SMEs to move cost-effectively to the more sustainable supply chains essential for the future.
Project: CONDUITS-DST: Further development of the CONDUITS Key Performance Indicators (Kapsch TrafficCom) (2012-2015) I. Kaparias
Cities today share common transport problems and objectives with respect to road traffic management, and put great focus on Intelligent Transport Systems (ITS). The project involves the implementation of the FP7 CONDUITS project, the CONDUITS-DST spinoff project, sponsored by Kapsch TrafficCom, extends the CONDUITS framework from a tool for evaluating existing systems to a tool for evaluating future systems by integrating the CONDUITS KPIs with traffic micro-simulation. The outcome is a predictive evaluation tool for road traffic management and ITS, called CONDUITS_DST, which links traffic micro-simulation with other predictive models (emissions, accidents, accessibility etc.). The research provides performance evaluation framework for urban traffic management and ITS in a novel decision support tool, using the output of microscopic and macroscopic traffic simulation tools. City's involvement is in the area of the development of methodologies for predictive evaluation and the conduct of the validation case studies.
Networks and Cyber Security
Project: REACH (Rural broadband intErnet Access using Cooperative mesh networking in wHite space spectrum), EU-India Research and Innovation Partnership, V. Rakocevic
Recently, the Centre has been involved in a successful bid for the project REACH (Rural broadband intErnet Access using Cooperative mesh networking in wHite space spectrum). This project will develop a strong cluster-to-cluster partnership between research centres in the EU and India to develop advanced technical solutions for providing high-speed broadband Internet access in rural India by deploying cooperative mesh networking in the unlicensed (white space) spectrum. The project is supported by the EU-India Research and Innovation Partnership and includes ten partners from India and the EU countries.
Funded collaborations (V. Rakocevic): The Centre has a longstanding collaboration with the T-Systems Research Labs in Germany (since 2006), with several research projects on the operation of WiMAX and LTE networks jointly completed during the last 10 years.
Project: EPSRC: App Collusion Detection (ACID), (2014-2017, City: £280,000), T. Chen (PI)
City is collaborating with Swansea U., Coventry U., and McAfee/Intel to develop new detection methods for Android apps that are capable to colluding together to overcome the permission restrictions in Android smart phones and tablets. Permissions is one of Android's built-in security mechanisms to keep mobile devices safe from malicious apps. However, colluding apps have been able to work together for malicious actions, bypassing permissions, and traditional antivirus software Is not able to detect collusion. McAfee will help to commercialise the new detection methods in their Global Threat Intelligence System. Prof T. Chen is a co-director of the Cyberterrorism Project (www.cyberterrorism-project.org).
Mathematical Methods and Optimisation
Project: A-DAP, Marie Curie Intra-European Fellowships (IEF) Call: FP7-PEOPLE-2012-IEF : "Approximate Solutions of the Determinantal Assignment Problem and distance problems" (2013-2015, City: €309,235) N. Karcanias (PI) and Dr. J. Leventides (Advanced Fellow)
The Determinantal Assignment Problem (DAP) provides an abstract formulation unifying the study of pole, zero assignment of linear systems. DAP is equivalent to finding solutions to an inherently non-linear problem and its determinantal character demonstrates the significance of exterior algebra and classical algebraic geometry. The research aims to provide solutions for non-generic frequency assignment problems and handle problems of model uncertainty. This is achieved by developing robust approximate solutions to the purely algebraic DAP framework and thus transforming existence results and general computational schemes to tools for control design. The research involves the computation of distances between Grassmann and families of Linear varieties, introducing a new robust methodology for Global Linearisation using homotopy theory and finally developing an integrated framework for approximate solutions of DAP.
