摘要
本文利用（Ｊ，Ｊ＇）－无损矩阵的性质，研究了基于散射模型的Ｈ∞控制系统的闭环稳定性，获得了广义对象的散射模型为（Ｊ，Ｊ’）－无损的Ｈ∞控制问题可解的充要条件．与文［１］中关于广义对象为一类内矩阵的Ｈ∞控制问题求解的结果相比，本文的结论对广义对象的限制要弱．
The closed-loop stability of Had control systems based on chain-scattering representation isstudied by using the property of (J,J')-lossless matrix. A necessary and sufficient condition for the H∞control systems where the chain-scattering representation of generalized plant is a (J,J')-lossless matrixis obtained. In comparison with the result of [1] about the stability of H∞ control problem for an inner system,the constraint on the generalized plant is weak.
