摘要
讨论区域极点约束下，含结构参数扰动的不确定线性离散系统的鲁棒控制问题，即设计一鲁棒状态反馈控制器，使线性离散系统在可允许的参数扰动下，闭环矩阵极点始终位于一预先给定的圆形区域中，从而闭环系统具有期望的动态性能．上述控制目的可通过求解一含参数的代数离散Ｒｉｃｃａｔｉ方程达到．
This paper considers the robust control problem for uncertain linear discrete-time systems with regional constraints. The problem we address is to design the robust state feedback controller such that the closed-loop poles are placed within a specified disk for all admissible perturbations, and hence the closed--loop systems will possess the desired dynamical performance. It is shown that the control object can be achieved by solving an algebraic Riccati equation with uncertain parameters.
