不确定系统的动态输出反馈圆形区域极点配置

Robust Circular Pole Placement via Dynamic Output Feedback for Perturbed Linear Systems

本文对一类不确定线性系统研究了实现鲁棒圆形区域极点配置的动态输出反馈控制律设计．通过一个修正的Ｌｙａｐｕｎｏｖ方程，给出了鲁棒控制器的存在条件．该修正Ｌｙａｐｕｎｏｖ方程的逆解就是期望的动态输出反馈控制器的一般解．

This paper discusses design of robust dynamic output feedback control laws for a class of perturbed linear systems that place the closed-loop poles in a specified circular region of complex plane. Utilizing a modified Riccati eqution, existence conditions of the robust controller are given,and the general solution of the robust controller is parameterized by the inverse solution of this modified Lyapunov equation.
