| 摘 要： | 本文考虑了一类基于观测器的线性不确定系统的正实控制问题，其中它的不确定性更具一般性．把这类问题转化为带有常量参数的系统的正实控制问题，通过求解线性矩阵不等式得到控制器参数的解，设计的此类基于观测器的控制器，使得闭环系统稳定且扩展严格正实．最后通过仿真算例进一步验证了该控制方案的有效性．

| Abstract: | The observer-based positive real control problem for a class of linear systems with general uncertainties is considered.By casting this problem into a class of positive real control problems with scaling parameters,uncertainty-independent solutions are established and expressed in linear matrix inequalities.The problem we addressed is to design observer-based dynamic output-feedback controllers,so that the closed-loop system extends strictly positive realness.Then the numerical example is given to demonstrate the validity of the approach. |
