摘要
针对一类带有时变时滞的不确定Takagi-Sugeno(T-S)模糊系统,考虑了其无源动态输出反馈控制器的设计问题。采用Lyapunov稳定性理论,由线性矩阵不等式方法得到了时滞依赖的无源稳定性分析结果,以及该类模糊时滞系统的动态输出反馈控制器存在的充分条件。该动态输出反馈控制器能保证闭环系统的鲁棒稳定和无源性。数值算例证明了该设计方法的有效性。
This paper considers the design problem of passive dynamic output feedback control for uncertain Takagi-Sugeno（T-S）fuzzy systems with time-varying delays.Via the application of Lyapunov stability theory and the linear matrix inequality techniques,delay-dependent sufficient conditions are given for the passive stability analysis and the existence of the dynamic output feedback controllers.The dynamic output feedback controller designed here guarantees the robust stability and the passivity of the closed-loop system.A numerical example is given to illustrate the effectiveness of the design approach here.
