| 摘 要： | 讨论了应用马尔可夫模型方法分析容错导航系统可靠性的化简问题。提出了首先应用马尔可夫模型方法分析每种组件的任务可靠性 ,然后应用组合分析的方法综合得出整个系统任务可靠性的方法 ,它可以大大简化可靠性的分析过程 ,减少计算量。最后 ,以四余度双敏感轴捷联惯导系统为例 ,对在不同条件下应用普通马尔可夫模型方法和化简的方法分析系统可靠性的精度进行了仿真比较。

| Abstract: | This paper deals with the simplification of reliability evaluation of Markov process for fault tolerant navigation system. The simplified method first is used to calculate the mission reliability of each subsystem of the navigation system by the Markov process theory, then the mission reliability of the whole navigation system is calculated by the combination analysis method. In this way the calculation of the whole reliability can be simplified considerably. This approach is applied to the navigation system of four two-degree-of-freedom gyros (accelerometers). The results of the simplified method and the general Markov method are compared by simulation. |
