计算机控制系统的容错技术

Fault Tolerance Technique of Computer Controlled Systems

计算机控制系统的可靠性设计是实现柔性智能控制所面临的一个重要课题，而容错技术是系统可靠性设计的关键技术。本文在分析计算机系统可靠性设计的基础上，综述了容错技术的发展、研究的主要内容及实现的主要方法，对常用的几种容错结构进行了比较和评价。指出了对计算机系统进行容错设计必须解决的主要问题。

Reliability design of a computer controlled system is an important problem to realize flexible intelligent control. The fault tolerance technique is the key to enhance the reliability of a computer controlled system. Based on the analysis of reliability design this paper presents the development of fault tolerance technique,the main research contents and the realizing methods. The paper also gives the compare and the eveluation of some typical fault tolerance constructions,as well as points the main problems which have to be solved in the fault tolerance design of a computer controlled system.
