摘　　要：基于强严格正实引理使用线性矩阵不等式方法讨论了参数不确定线性系统鲁棒严格正实控制器的综合问题 ,提出了二次严格正实的新概念 ,证明了静态状态反馈解的存在性 。Based on the strongly strictly positive real lemma, this paper addresses the synthesis problem of robust strictly positive real controllers for a class of linear systems with norm bounded parameter uncertainties using linear matrix inequality based approach. It shows the existence of static state feedback solution. A notion of quadratic strictly positive realness has been presented. The existence condition and the synthesis method of quadratic strictly positive real controllers via state feedback is given.
