基于采样数据观测器控制设计

Observer Based Data Sampled Design

为预测采样系统实际状态,本文基于采样数据构造系统状态观测器,研究了线性系统基于采样数据观测器反馈镇定问题。先给出线性系统采样观测器的设计,并利用李雅普诺夫泛函方法,结合线性矩阵不等式技术,给出采样数据观测器和控制器设计方案,并通过仿真算例进行验证,仿真结果表明,在同一时刻,系统的状态能够及时达到稳定,证明本文所设计的控制器是有效合理的。

This paper mainly discusses the stabilization of linear systems based on data-sampled observer. Firstly, we propose the design scheme of the linear data-sampled observer based on the Lyapunov function and LMI methods. Then, a control scheme is presented via observer-based state feddback. Finally, a digit- al example is used to illustrate the effectiveness and feasibility of our approaches.
