Abstract: A D-stable robust fault-tolerant controller is designed for discrete multi-time-delay systems.Firstly,the sufficient condition of D-stability is given for sensor failure.Secondly,the condition is generalized to the systems for actuator failure and uncertainties.This robust fault-tolerant controller can make the systems remain stable and have satisfying performances.Moreover,the controller can be realized easily in practice.Finally,an illustrative example is given to demonstrate the correctness of the proposed method,and the result of the example is analyzed.
摘要: 针对离散多时滞系统,设计了一种D稳定鲁棒容错控制器。首先以传感器失效为例,推导出了使系统D稳定的充分条件。然后依次推广到执行器失效以及系统参数不确定的情况。所设计的鲁棒容错控制器既能保持系统的稳定性,又能使系统满足一定的性能要求,且工程上易于实现。最后通过仿真示例验证了文中方法的正确性,并对仿真结果进行了分析。
