双时滞不确定离散系统的满意容错控制

摘要

为了满足工业实际中要求容错控制策略不仅保证故障模式下系统的稳定,同时还须满足一定的性能指标或约束条件的要求,针对同时具有状态和控制时滞的不确定离散时滞系统,在一般执行器故障模式下,研究了基于状态反馈的H∞满意容错控制问题,并用仿真示例验证方法的有效性.%The tolerant control strategy for process control system should not only guarantee the stability of fault systems,but also satisfy some performance indices or constraints. The satisfactory fault-tolerant control methods with multi-indices constraint are investigated. For uncertain discrete time-delay systems against actuator failures, the state-feedback based H∞ satisfactory fault-tolerant control method and guaranteed cost control method are investigated.Numerical examples are given to illustrate the validity of the results.
