Adaptive fault-tolerant flutter control based on dynamic output feedback

In this paper, the problem of two-dimensional wing flutter control with sensor , actuator failures is studied. Firstly, the aeroelastic equations of motion for two-dimensional wing with plunge and pitch are established; then the wing flutter model with failure modes is established considering the failure modes of sensor and actuator. Secondly, by designing a novel adaptive fault-tolerant controller, the wing flutter can be suppressed effectively and the external disturbance can be dealt with successfully. The stability of the system is proved by the constructed Lyapunov function. Finally, numerical simulation results show that the adaptive flutter fault-tolerant controller can effectively suppress wing flutter when sensors and actuators fail , the controller has good robustness to the changes of external disturbances.(c) 2022 The Franklin Institute.
