容错控制系统的可靠性建模及模型化简

在容错控制系统的设计过程中，进行系统的可靠性建模和分析求得容错控制系统可靠性是一项非常重要的工作。它是许多设计工作，如设计方案的选择优化和一些设计参数的确定等的重要理论依据。在容错控制系统的可靠性分析中，利用马尔柯夫过程理论对容错控制系统进行可靠性建模能够较为真实地描述系统的实际工作情况，但是由于容错系统为了达到高可靠性而有采用了大量的冗余配置及重构技术，使得该可靠性模型往往变得相当复杂。因此，对

Reliability Model Building and Its Simplification of Fault Tolerant Control System

To the design and the analysis of fault tolerant control system, it is very important to build and analyze reliability model. The high levels of reliability and availability required lead to sophisticated fault tolerant redundancy and recovery techniques. In the reliability analyzing of such a system, Markov process theory can be applied to describe the original working condition of the system. But any analytic model of such a system has a large number of states, making the solution computationally intractable. This leads to the need for simplification techniques.
