摘　　要：讨论了一类含有不确定参数的多时滞线性系统的鲁棒H∞ 控制问题 ,分别给出了全维鲁棒H∞ 动态输出反馈控制器和静态状态反馈控制器的设计。所设计的控制器使得相应的闭环系统对一切时滞和所有允许不确定参数保持内稳定 ,并且闭环系统从扰动到受控输出之间传递函数的 H∞In this paper, the robust H\-∞ feedback controllers for the linear systems with multiple time-delays and uncertainties are designed. Based on the algebraic Riccati equations, the robust H\-∞ dynamic output feedback controller and robust H\-∞ static state feedback controller are constructed respectively, under which the closed-loop systems are of internal stability and the H\-∞ norm of the transfer function from the disturbance to the controlled output is reduced to a given level for all admissible uncertainties and positive constant delays.
