Event-triggered adaptive fuzzy tracking control for high-order nonlinear switched systems
The issue of event-triggered adaptive fuzzy tracking control for high-order switched nonlinear systems is discussed.The uncertain nonlinear functions are approximated by utilizing fuzzy logic systems.In particular,a finite-time convergence filter is proposed to avoid the problem of repeated differentiation of virtual controllers.On the basis of the backstepping control technique and the common Lyapunov function approach,a fuzzy finite-time dynamic surface control scheme is developed.The proposed control scheme can ensure the all the signals in closed-loop systems are bounded and tracking error converges to an area of zero in finite time.Numerical examples further illustrate the effectiveness of the proposed control strategy.
