摘要
针对奇异大系统,研究其分散鲁棒H∞广义输出反馈控制问题。基于有界实引理将存在分散鲁棒H∞广义输出反馈控制器的条件归结为一组矩阵不等式,采用同伦迭代算法求解分散鲁棒H∞广义输出反馈控制器,使闭环大系统鲁棒稳定,并满足给定的H∞性能指标。最后用数值例子说明了该设计方法的有效性。
The problem of decentralized robust H∞ descriptor output feedback control for singular large-scale systems is presented. Based on the bounded real lemma, the design of decentralized robust H∞ descriptor output feedback controller is reduced to a feasibility problem for matrix inequalities （MI）. The controller is solved iteratively by homotopy method, which makes the closed-loop large-scale system robustiy stable and satisfy the given H∞ performance. The given example shows the effectiveness of the method.
