时滞系统输出反馈无源控制器设计

Design of the Output Feedback Passive Controllers for Time-delay Systems

研究一类线性时滞系统的输出反馈无源控制问题 .通过采用 L yapunov稳定性理论和线性矩阵不等式方法 ,给出了使闭环系统二次稳定且严格无源的静态或动态输出反馈控制器存在的充分条件 ,这两种控制律的设计问题最终转化为线性矩阵不等式的可行解问题 .

This paper focuses on the problem of output feedback passive control for a class of linear time-delay systems. By using Lyapunov stability theory and linear matrix inequality (LMI) approach, sufficient conditions are given for the existence of static or dynamic output feedback controllers which render the closed-loop system to be quadratically stable and strictly passive. The design of the two control laws is transformed into finding a feasible solution of LMIs.
