Abstract

This paper considers the problem of adaptive prescribed performance control for a class of switched nonlinear systems with time-varying delays and unmodeled dynamics. Fuzzy logic systems are introduced to deal with the unknown nonlinear terms. Utilizing dynamic surface control and convex combination method, a state-feedback controller is constructed. It is proven that all signals of the closed-loop system are bounded. Finally, simulation results are given to show that the proposed scheme is effective.
