针对带电传操纵系统人-机闭环系统稳定性问题,讨论了人-机闭环系统稳定性的研究方法。在分别建立飞机本体、操纵系统和驾驶员模型的基础上,建立了综合考虑非线性因素的横航向补偿控制模型。以横向滚转操纵为例,在时域内对系统进行了动态仿真,研究了驾驶员滞后时间对人-机闭环系统稳定性的影响。仿真结果表明,该方法用于研究人-机闭环系统稳定性是可行的和有效的。
Aiming at the stability problem of the man-machine closed-loop system with fly-by-wire system, the research method of the stability of the closed-loop system of human-machine is discussed. Based on the establishment of the aircraft body, the control system and the driver model respectively, a transverse compensation control model considering nonlinear factors is established. Take horizontal roll control as an example, the dynamic simulation of the system is carried out in the time domain, and the influence of driver lag time on the stability of the closed-loop system is studied. The simulation results show that this method is feasible and effective for studying the stability of the closed-loop system.
