Abstract: 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 condition 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 closed-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.
