摘要	A staircase membership functions-based Hcontrol method was proposed for discrete T-S fuzzy control systems. In order to increase the flexibility of controller design, a fuzzy Lyapunov function was implemented as the candidate of Lyapunov function. And the non-parallel distributed compensation controller was used to close the control loop. Furthermore, staircase membership functions were used to approximate the membership functions of discrete T-S fuzzy model. Due to the discreteness and finiteness of the values of staircase membership functions, the fuzzy matrix inequalities which describe the stability and performance of the closed-loop system can be converted to some linear matrix inequalities. Since the information of membership functions was introduced into the controller design, the conservative of the controller design was reduced. Compared with traditional Hcontrol methods, the presented method could design a fuzzy controller with lower Hindex. A numerical simulation example was given to show the effectiveness of the proposed method.
