| 摘 要： | 研究了状态反馈控制饱和单输入离散系统和动态输出反馈单输出饱和离散系统的稳定性，给出了这两类系统是全局渐近稳定还是区域渐近稳定的充分性条件，且对区域渐近稳定的情况计算其不变吸引椭球，对控制饱和系统，运用Ricatti方程迭代法设计控制器以使所得椭球尽量大；最后用算例说明方法的有效性．

| Abstract: | To discuss the stability for a state-feedback single-input discrete-time system subject to actuator saturation and a dynamic output-feedback single-output discrete-time system with output saturation,the paper presents a sufficient condition which guarantees the two systems are global-asymptotic-stabilization(GAS) or regional-asymptotic stabilization(RAS),calculates an invariant attractive ellipsoid for the case of RAS,gives an iterative Ricatti equation algorithm to find such a controller that supports an ellipsoid as large as possible for the system with actuator saturation.At last,this paper illustrates the effectiveness of our approach with example. |
