中文摘要：
以两个子系统组成的序列连续系统为研究对象,提出了一种新的容错控制方法.如果两个子系统中的任何一个发生故障,用基于自适应观测器的方法诊断出发生的故障.另一个无故障的子系统利用故障诊断信息和其它测量信息进行控制器重组,实现了序列连续系统的容错控制.当发生故障的子系统不能自行修复故障,或修复故障需要很大的时间延迟时,传统的复杂系统容错控制方法将无能为力.本文所提出的方法拓展了复杂系统容错控制的适用范围.计算机仿真结果表明了本文所提出方法的有效性.
英文摘要：
A new fault tolerant control method is proposed for a sequential continuous system which includes two subsystems. The fault of either of the two subsystems can be diagnosed using the adaptive observer method. The controller reconfiguration can be carried out by the other faultless subsystem using the fault estimation information and other measured information, leading to the fault tolerant control of the sequential continuous system. If the fault in the subsystem can not be repaired or there is long time delay when the fault is compensated, traditional fault tolerant control methods of the complex systems can not be used. Fault tolerant control scope is extended by the proposed method. Computer simulation results illustrate the validity of the method.
