摘　　要：研究了具有控制器增益变化的离散时滞系统鲁棒H∞可靠控制问题。在考虑更一般、更实际的执行器连续故障模型的基础上,分别给出了系统控制器具有乘性摄动和加性摄动时的H∞可靠控制器存在的充分条件;设计的可靠控制器不仅能够保证系统稳定,且满足H∞性能约束。最后仿真实例说明了方法的有效性。The problem of Ho^robust reliable control is studied for the discrete time-delay systems with controller gain variations. Based on a more practical and general actuator failure model which is called continuous failure model, the sufficient conditions for the existence of H~, eliable controllers are given with additive and multiplicative perturbations state feedback respectively. The designed reliable controllers can make the closed-loop systems as- ymptotic stability and satisfy H~ performance constraints. An example is given to illustrate the effectiveness of the proposed method.
