On the robustness of stability of fuzzy control systems

In this paper, the robustness of stability of fuzzy control systems is discussed. Sufficient conditions for fuzzy control systems to be stable in the sense of bounded-input bounded-output stability are provided based on the concepts of the Lyapunov direct method. The robustness of stability to parameter variations of the fuzzy control systems is studied. And finally simulation examples are included to support the presented propositions.
