Adaptive fault‐tolerant control of switched nonlinear systems based on tuning function method

This paper solves the problem of adaptive fault‐tolerant control of uncertain switched nonlinear systems with unknown parameters and actuator failures. Based on the multi‐Lyapunov function method, a novel adaptive switched controller with tuning function is designed using the backstepping procedure. Meanwhile, a switched fault‐tolerant adaptation mechanism is also given to compensate the fault efficiency. Furthermore, it is certificated that all the signals of the closed‐loop system are uniformly bounded and the tracking error restrain to a small neighbor. Finally, the simulation results verify the feasibility of the proposed method.
