Stability Analysis and Systematic Design of T-S Fuzzy Control Systems
T-S模糊控制系统的稳定性分析及系统化设计

The properties of fuzzy control systems employing two-overlapped fuzzy partition (TFP) inputs are studied, and a new sufficient condition to check the stability of a T-S fuzzy control system is proposed. This cor dition only requires finding a common positive-definite matrix in each maximal overlapped-rule group. It can reduce the difficulty of former stability analysis approaches. Using the method of parallel distributed compensation (PDC) , the stability analysis of clesed-loop T-S fuzzy control systems and the systematic design of fuzzy controllers are investigated farther. The simulation results of two examples show that these methods are effective.
