Angle of Attack Tracking Control Considering Actuator Saturation

Based on the design of the nonlinear dynamic inverse controller, the L1 adaptive controller is designed to compen.sate the inverse error and external interference in order to improve the robustness of the control system. In order to ensurethe stability of the system, a Pseudo Control Hedging compensation signal is introduced for actuator saturation constraint,and the reference input is modified, so the method is capable of avoiding control saturation at all time. Finally, the angle ofattack command tracking control is taken as an example for simulation verification. Simulation results show that the L1 adaptive compensation with Pseudo Control Hedging compensation keeps good command tracking performance for the angleof attack tracking control.
