摘要
为了提高动态系统的可靠性,研究了多状态时滞系统的主动容错控制.给出了基于广义内模控制设计的容错控制器设计方法.该容错控制器由两部分构成,分别针对系统的性能和鲁棒性.只有当系统发生故障时,控制器中针对鲁棒性(容错性)的部分才会起作用,从而保证系统在没有故障时具有尽量好的性能,而当故障发生后具有容错功能.通过一个仿真算例,验证了方法的有效性.
This paper proposed an active fault tolerant control (FTC) design method for multiple state delay systems based on generalized internal model control (GIMC). This controller includes two parts, one part for performance and the other for robustness. The part for robustification (fault accommodation) will be active when there are faults. This ensures that the system without fault has good performance index. When there are faults, the post-fault system has the ability to tolerate them. Simulation results are given to illustrate the efficiency of the method provided.
