Sliding mode control of fuzzy dynamic systems

A sliding mode control scheme for a class of complex nonlinear systems with T-S fuzzy models is proposed in this paper. It is shown that, by using the concept of extreme matrices to determine the upper bound information of the interactions of the fuzzy subsystems, a simple, yet constructive sliding mode control scheme can be developed to guarantee the asymptotic stability and robustness of the closed-loop system. Simulation results are presented in support of the proposed scheme
