摘要 针对一类不确定连续关联系统,当不确定性满足矩阵多胞型结构时,对其保性能控制进行了研究.根据给定的二次型性能指标,定义了系统的分散鲁棒保性能控制器.然后,利用不等式技巧以及LMI(线性矩阵不等式)的处理方法,得出了不确定连续关联系统存在分散鲁棒保性能控制器的判据和设计方法.有关算例验证了所得结果的可行性和有效性. Guaranteed cost control was discussed for a class of uncertain continuous large-scale systems, and the uncertainty under consideration was matrix polytope structured. According to a given quadratic performance index, decentralized robust guaranteed cost controller is defined. By using the technique of inequalities and methods of LMI （ Linear Matrix Inequality）, existence condition and design method of decentralized robust guaranteed cost controller are proposed. A relative example demonstrates the feasibility and effectiveness of the results obtained.
