Abstract:An adaptive backstepping failure compensation tracking scheme is proposed for a flying wing aircraft nonlinear longitudinal dynamics in this paper, with considering the actuator stuckness or loss of effectiveness, saturation nonlinearity of the actuators and prescribed performance bound(PPB)of the closed loop system. The prescribed performance bound is designed to guarantee that the tracking errors are constrained within prespecified envelope, second-order low-pass command filters are introduced to avoid saturation of the actuators, control allocation is designed to reduce the effect on the lateral motion of the aircraft. The proposed adaptive backstepping failure compensation tracking law can guarantee the asymptotical tracking of the reference signals. Simulation results show the effectiveness of the proposed control scheme. © 2018, Editorial Department of Control Theory & Applications South China University of Technology. All right reserved.
