摘要：
This article investigates the robust stabilization problem and proposes a state observer-based output-feedback controller for a class of nonlinear switched T-S fuzzy systems with actuator dead zone and constant time delay. The nonlinear switched fuzzy systems consist of several switched modes, and each switched mode is linear system. Based on parallel distributed compensation (PDC) technique, the robust fuzzy control law and switching law are constructed via using the Lyapunov function method, respectively. The sufficient stability conditions are proposed and parameterized in terms of linear matrix inequalities (LMIs), which can be solved using the convex optimization techniques. Numerical simulation results illustrate the effectiveness of the proposed scheme for the nonlinear switched T-S fuzzy systems.
