摘要
在飞行控制系统中,飞行控制计算机起着核心作用,要求具有极高的可靠性,整个系统的失效率要求小于10-8/小时。为了满足此要求,飞控计算机系统一般采用余度技术。本文结合工程实践,讨论了一个高性能四余度容错计算机的系统结构,建立了考虑系统瞬态故障恢复和多故障处理能力的多阶马尔科夫可靠性模型,并给出了数学计算结果。
The flight control computer plays a kernel role in flight control systems. Ultra reliability is needed to ensure that the ratio of system failure is less than 10-8 /hour. To meet this requirement, redundancy techniques are used in the design of the flight control computer. This paper, with the experience in project practice, describes the system architecture of the quad-redundant fault-tolerant computer and sets up the Markov model which takes the transient fault and multi-fault states into account. In the end the results are given.
