容错控制系统的可靠性研究
Study on the Reliability of Fault-tolerant Control System
-
摘要: 以是否满足性能指标要求为评判标准 ,研究了容错控制系统可靠性概念的内涵和定义。基于系统的状态划分 ,以统计理论的观点分析了容错控制系统中的故障概率、容错能力和可靠性问题。并利用马尔柯夫链对其进行了可靠性问题的建模。Abstract: The intension of concept of reliability and the definition of reliability are discussed according to whether the fault tolerant control system satisfies performance requirement. The fault probability, the degree of fault tolerance and problem of reliabilty in the fault tolerant control system are analyzed in the view of statistics. And Markov chain is used to analyze and model for the reliability problem.
