| 摘 要： | 研究了离散T-S模糊控制系统的稳定性分析及控制器设计问题。考虑到系统状态不易测量,利用输出反馈设计模糊控制器;基于模糊Lyapunov函数方法提出一新的稳定性判别条件,利用矩阵变换把该条件转化为一组线性矩阵不等式(LMIs),该条件具有更大的宽松性。最后,一个仿真实例说明了本算法的有效性和优越性。

| Abstract: | The stability analysis and controller design problem of discrete T-S fuzzy control systems were discussed.Considering that the system state is difficult to be measured,by using output feedback method,a fuzzy controller was designed.A new stability condition was proposed based on fuzzy Lyapunov function approach,and further,by using matrix transformation,it was converted to a set of linear matrix inequalities (LMIs),which is more relaxed.The simulation results illustrate the effectiveness and merits of the proposed method. |
