Anti-windup smooth switching controller design of morphing aircraft

Considering the attitude-stabilization during the transformation process of morphing aircraft with the effect of large scale change of system dynamic and constrained actuator output amplitude, based on mode-dependent average dwell time approach, a design methodology of anti-windup smooth switching controller is proposed. First, a class of chained smooth switching system model is established, which can reflect aerodynamic coefficient transition of morphing aircraft in the transformation process more precisely and reduce conservatism of controller design. Based on the model, the sufficient condition to ensure the finite-time boundedness and robustness of chained smooth switching system can be obtained via the mode-dependent average dwell time approach. Finally, design of anti-windup compensation is proposed. Also, the problem of anti-windup controller design is translated to problem of optimization with linear matrix inequalities constraint. Finally, simulation results are given to demonstrate the efficiency of the proposed controller design approach.
