ABSTRACT: Based on the uncertain state of T-S fuzzy system, it was designed of the memory fuzzy feedback controller to achieve guaranteed cost control of the system. Firstly, by constructing a Lyapunov function and based on the Laypunov stability theory, it was proved that the closed-loop system is asymptotically stable through the application of this memory feedback controller, at the same time, gave an upper-bound for the given guaranteed cost control. Secondly, by using the linear matrix inequality (LMI) technique in MATLAB, the feedback controller gain would found out. Finally, the simulation example is given to illustrate the validity of the proposed method.
