Robust Controller Design for Switched Fuzzy System with Uncertain Input

Robust switching stabilization control of a class of switched fuzzy systems with uncertain input is considered. Switched fuzzy system describe its subsystems which each subsystem is a fuzzy T-S model. There exit not only disturbances of switched fuzzy systems which do not satisfy the supposed matching situation and include uncertainties in the input condition, but also have the state matrix uncertainties. Now By using multiple Lyapunov function, the state-feedback switching robust controllers are designed. Moreover the switching law is studied out. With the given switching laws, the switching controller can ensure robust stabilization of the switched fuzzy states. Simulation results are provided that there explain the proposed effectiveness and signification.
