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。
In order to study the safety of carrier-based aircraft carrier, the issue of driver induced oscillation (PIO) of carrier-based aircraft is first proposed. Based on the research results of pilot-induced oscillation of land-based aircraft pilots, this paper analyzes the problems of carrier-based aircraft and land- On the similarities and differences between the structure of the rate limiter pre-filter to improve the control loop in the servo speed protection structure, focusing on the carrier aircraft during the decline of PIO may occur during the simulation and evaluation using the Smith criterion The oscillation trend of the process illustrates the impact of the PIO on the ship safety during the decline and validates the effectiveness of the proposed precautionary approach.
