摘要
本文应用人—机系统闭环控制原理,对J—7Ⅰ飞机的驾驶员诱发振荡(PIO)问题进行了研究。首先,建立了驾驶员—操纵系统—飞机本体组合系统及大气紊流的数学模型。其次较详细地分析了J—7Ⅰ飞机的驾驶员诱发振荡问题,复现了几次较为典型的PIO现象,找出了PIO的敏感区及排除PIO的方法;最后对理论研究的结果进行了模拟试验,验证理论分析的正确性.
In this paper, the research for J-7Ⅱ's Pilot-Induced Oscillation (PIO) is carried out by means of the theory of pilotvehicle system. First, the mathematical models included the pilotcontrol system-airframe and the air turbulence are set up. Second, the J-7Ⅱ's PIO is analyzed in detail and several typical PIO are reproduced. The sensitive scope of PIO within the whole flight envelop are found, and find the schemes to eliminate J-7Ⅱ's longitudinal PIO. Finally, the results of research in theoretical are verified by RJ-Ⅱ A fixed based simulator.
