中文摘要

      本文提出了一种统一的鲁棒严格正实性判定准则，既适用于连续系统，又适用于离散系统，在此准则基础上，形成了设计鲁棒严格正实滤波器和补偿器的设计方法.当考虑到系统是线性参数摄动系统或由若干独立线性参数摄动系统串联而成的，则本文给出的是端点结果.

英文摘要

      In this paper，an uniform criterion for robust strict positive realness is presented which is applicable not only to continuous systems but also to discrete systems. Based on it，the methods to design the robust strict positive real filter and compensator are formed. When the considered systems is one with lineary dependent coefficient perturbations or is one formed by cascade of several independent subsystems as above， the results given by this paper are the extreme results.
