| 摘 要： | 为了研究舰载机着舰安全性,首次提出了舰载机的驾驶员诱发震荡（PIO）问题,结合对陆基飞机飞行员诱发振荡的研究成果,分析了舰载机与陆基飞机在该问题上的异同点,构造了速率限制器前置滤波器来改进控制回路中的舵机速率保护结构,重点对舰载机着舰下滑过程可能发生PIO情况进行了仿真分析,并利用史密斯准则评估了过程的振荡趋势,说明了下滑过程发生PIO对着舰安全的影响,同时验证了所提出的防范方法的有效性。

| Abstract: | Aimed at studying the safety in Carrier Landing,this paper puts forward the Pilot Induced Oscillation problem firstly,integrates these results of PIO problem of land-based aircraft,analyses the differences of PIO problem between carrier-based and land-based aircraft,constructs a rate-limiter pre-filter to improve the actuator rate protecting configuration,simulates and analyses the PIO trend of slope in carrier landing process.Finally,the concussion trend in carrier landing is evaluated with the Smith Criterion,analyses the affection of PIO to safety in carrier landing,and validates the effectiveness of the measure. |
