摘要：

应用线性矩阵不等式方法研究TS模糊系统的H∞保成本容错控制器的设计问题。针对含有容许的不确定参数和可能的执行器故障的模糊时滞系统，在考虑保成本函数取得最小上界的基础上，兼顾系统的H∞性能。以线性矩阵不等式的形式给出TS模糊系统H∞保成本容错控制器存在的充分条件,把控制器的设计问题转化为线性矩阵不等式的可行解问题。通过例子验证了所给出的H∞保成本容错控制器设计方法的可行性和有效性。

Abstract:

By using the LMI method，the problem of H∞ guaranteed cost fault tolerant controller designs for TS fuzzy system is studied. The fuzzy timedelay systems with admissible uncertain parameters and actuator failures are dealt with, and the least upper bound of the guaranteed cost function and H∞ performance are considered simultaneously, the sufficient condition for the existence of the H∞ guaranteed cost fault tolerant controller for TS fuzzy systems is given in term of LMIs. The problem on designing a controller is transformed into a linear matrix inequality (LMI) feasibility problem．The simulation example shows the feasibility and effectiveness of the design procedures.
