摘要
本文建立了包括非线性环节在内的横航向驾驶员—操纵系统—飞机本体组合系统的数学模型,采用闭环控制原理,对JJ-7飞机横航向驾驶员诱发振荡PIO问题进行了研究,并详细地讨论了驾驶员参数及其各种操纵动作、操纵系统和飞机本体气动参数对横航向PIO的影响,探讨了横航向PIO产生的机理。文中以JJ-7飞机为例,采用时域法在整个飞行包线各点进行了检查,并用固基飞行模拟器进行模拟验证。其结果与理论计算结果相一致。
The mathematical model of pilot-control system-airframe included nonlinear link is set up, by use of the closed-loop control priniciple in this paper. Then, the study of lateral-directional pilot-induced oscillation(PIO) is carried out. The influences of pilot parameters and their control action, control system parameters and aeronynamic derivaties on the lateral-directional PIO are analysed in detail. As an example, the lateral-directional PIO within the whole flight envelope boundary of JJ-7 aircraft are checked by use time domain methed, and tested by fixed-base simulator RJ-Ⅱ. The results of simulated are the same as those of calculation.
