摘要: 在分析飞机纵向摆动特性的基础上,建立了考虑非线性与随机性的人机闭环系统模型;提出了用双指数函数分布法确定驾驶员排除某事件引发纵向摆动的条件概率的计算方法,采用马尔可夫链建立了飞行安全评估模型;最后给出了算例。

Abstract: Based on the analysis of the feature for longitudinal oscillation, a pilot-aircraft model taking account ofnonlinearity and randomicity is established. A dual-exponential function is presented to calculate the conditionalprobability of eliminating longitudinal oscillation by pilot because of undesired events, and then a flying securitymodel is built to apply Markov chains. An example is given in the end.

Key words: Markov chains, longitudinal oscillation, dual-exponential function, flying security
