摘要
为了保证系统的稳定性和解决系统执行器失效的问题,针对一类线性广义时滞不确定系统,研究了在有记忆状态反馈作用下和执行器失效情况下的鲁棒容错控制问题。在采用具有更广泛意义的执行器故障模型下,给出了线性不确定时滞广义系统对执行器故障保持渐近稳定并且满足给定干扰衰减指标的鲁棒控制器的存在条件和设计方法。仿真结果验证了该方法的可行性和正确性。
In order to improve the reliability of the control system and to solve the actuator failures problem,this paper discussed the problem of robust fault-control for a class of uncertain time-delay singular systems with memory state feedback.It adopted a more general fault model of actuator failures,and gave the sufficient condition for robust fault-tolerant control in existence so that the systems could keep asymptotically stable against actuator failures and satisfy disturbance attention index prescribed.The simulation results verify the effectiveness and feasibility of the proposed approach.
