Stabilization Control for a Class of Switched Fuzzy Discrete-Time Systems

Stability issues for switched systems whose subsystems are all Sugeno fuzzy discrete-time systems are studied and new stabilization control results derived. Innovated representation models for switched fuzzy systems are proposed. The single Lyapunov function method has been adopted to study the stability of this class of switched fuzzy systems. Sufficient conditions for quadratic asymptotic stability are presented and stabilizing switching laws of the state-dependent form employed in PDC scheme are designed. Illustrative examples demonstrate the effectiveness and the feasible performance of the proposed synthesis through the respective simulation results.
