摘要
本文把多变量控制系统常出现的故障分为两类:1)第 i 个回路中传感器失效;2)第 j 个回路中执行机构失效。以线性时不变系统为研究对象,本文建立了故障系统的数学模型,提出了仍能保证系统稳定的控制器必须满足的准则,从而为设计具有容错能力的控制系统提供了理论依据。
In this paper we arrange the faults ordinarily occured in multi-variable control systems under two cate-gories:(1)invalidity of ith sensor,(2)invalidity of jth actuating mechanism.We take linear time-invariant sys-tem as object of investigation,formulate a mathematical model for fault systems,and present a stability criter-ion which the controller must satisfy.And thereby we provide a theoretical basis for failure-tolerant systemdesign.
