Speaker: Dr Shaojie Zhang (Nanjing University of Aeronautics & Astronautics)

Abstract:

Flying wing aircrafts have gotten wide research for their light weight, good stealth and flexible maneuverability, but the flying wing layout brings about some new control challenges. The design of prescribed performance adaptive backstepping longitudinal attitude control for a flying wing aircraft with actuator faults will be discussed in this seminar. By prescribed performance bound design, the tracking errors are restrained within prespecified envelope so that the maximum overshoot and convergence rate are within designated values. Faults of actuators are handled by adaptive control laws. Second-order low-pass command filters are introduced to limit the deflection angles of control surfaces and throttle levels, therefore avoiding saturation of actuators. In addition, control allocation strategy is designed to reduce the effect of faults on the lateral motion.
