摘要
文章针对一类具有不匹配时滞状态扰动的不确定系统,讨论了出现执行器故障状况下的鲁棒可靠镇定问题,在扰动有界但上界值未知的情形下,根据不确定性上界的估计值,设计了自适应鲁棒可靠控制器,使闭环系统在出现执行器故障状况下仍具有一致有界意义下的鲁棒稳定性。
For a class of time-delay uncertain systems with unmatched perturbations, the robust and reliable stabilization problem with actuator failures is discussed in this paper. In the case that the perturbations are bounded but the value of the bounds is unknown, adaptive robust and reliable controllers are designed based on the estimates of the upper bounds of the uncertainties. So the systems are robust stable in the means of uniform ultimate boundedness even if there exist possible actuator failures.
