摘要: 该文讨论不确定广义系统的最优保性能控制问题.给出了不确定广义系统保性能控 制器的两种设计方法:一是代数Riccati方程方法,给出了参数化的控制器;另一个是线性矩阵 不等式方法,给出了在使性能函数上界最小的意义下,最优控制器的设计算法,用实例演示了 该方法的有效性.Abstract: This paper presents results on optimal guaranteed cost control for a class of descriptor systems with norm bounded uncertainties. Two sufficient and necessary conditions for the existence of guaranteed cost control are obtained in terms of algebraic Riccati equation and linear matrix inequalities, respectively. Also, two procedures are proposed to select an optimal controller in the sense of minimizing the upper bound of the cost function. A numerical example is given to illustrate the methods.
