摘要
研究具有间歇性随机执行器故障的时滞系统的容错控制问题,通过假设执行器故障的发生满足Bernoulli分布,且发生的故障服从某种概率分布,建立具有一般性的执行器故障模型.利用时滞分段分析方法,有效地降低了时滞带来的保守性,并给出了故障分布依赖和时滞分段依赖的容错控制器解的存在条件.最后,通过算例验证了所提出方法的有效性.
This paper investigates a fault tolerant control for time-delay systems with intermittent actuators failure. Assuming that the actuators fault occurring obeys Bernoulli distribution, and the fault model obeys a certain probabilistic distribution, a general actuator-fault model is established. By employing delay-segmented method, a less conservative result is obtained. Based on fault-distribution-dependent and delay-segment-dependent methods, Sufficient conditions are derived for ensuring the stability of the systems with consideration of actuator failures. Illustrative examples show the effectiveness of the proposed design procedures.
