摘　　要：无源性不仅是系统的一个重要性质,而且是控制一个系统的重要途径.本文研究不确定时滞关联大系统的无源控制问题.利用Lyapunov泛函方法,通过求解线性矩阵不等式得到了无源控制器的显示表达,保证闭环系统稳定且严格无源.由于控制器采用动态输出反馈得到,因而控制器的设计也容易实现.最后用数值例子说明了得到定理的有效性.Passive is not only an important property of a system,but also an important approach to control a system.The problem of passivity control for uncertain interconnected systems with time-delays is studied.Employing Lyapunov functional method,the passive controllers are presented explicitly to make sure that the closed-loop system is stable and strictly passive by solving some linear matrix inequalities.Also,it presents the dynamic output feedback controllers and the parameters of the passive controllers are easy to be well set.A numerical example illustrates the availability of passivity and the design procedure of the passive controllers.
