摘要: 用矩阵不等式方法研究了数值界不确定性奇异大系统的广义输出反馈分散鲁棒H∞控制问题．基于有界实引理，提出了存在分散鲁棒广义输出反馈H∞控制器的矩阵不等式条件，并采用同伦迭代算法来获得控制器的参数．数值算例表明该方法求解简单，证明了它的有效性．Abstract: Decentralized robust H∞ descriptor output feedback control for singular large-scale systems with uncertain value bound is studied by matrix inequality approach.Based on the bounded real lemma,a sufficient condition for the existence of decentralized robust descriptor H∞ output feedback controller is obtained,which is expressed as matrix inequality.Parameters of the controller are solved iteratively by homotopy method.A numerical example shows that the method is simple and effective.
