Longitudinal Oscillation and Flying Security Evaluation

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 ;

Based on the analysis of the feature for longitudinal oscillation, a pilot-aircraft model taking account of nonlinearity and randomness is established. A dual-exponential function is presented to calculate the conditional probability of eliminating the longitudinal oscillation by pilot because of undesired events, and then a flying security model is built by use of Markov chains. An example is given in the end.
