摘要: 本文利用文献[10]中提出的线性系统特征结构配置结果和Hellman-Feynman定理,导 出了输出反馈系统闭环极点关于开环矩阵中受扰元素灵敏度的参数表达式,并在此基础上给 出了具有最小闭环极点灵敏度的输出反馈控制系统设计的一个算法.该算法简单、有效,且具 有较好的"最优性".Abstract: Based on the eigenstructure assignment result for linear systems proposed in [10] and the Hellman-Feynman Theorem, the parametric representations for the sensitivities of the closed loop poles, with respect to the perturbed elements in the open loop system coefficient matrices, of an output feedback control system are established. With these representations, an algorithm for design of control systems with minimum sensitivities of the dosed loop poles by using output feedback is presented. The algorithm is proved to be simple, effective and have better "optimality".
