摘要: 现代飞机采用放宽静稳定性构型和侧杆控制器操纵,使得舵面速率饱和引起的驾驶员诱发振荡(PIO)成为影响飞行品质的一个重要因素。针对舵面速率饱和引起的Ⅱ型PIO问题,设计了主动侧杆人感系统,其弹性系数随着舵面偏转速率饱和的发生而改变,从而达到抑制速率饱和的作用。基于主动侧杆引导下的人机闭环系统模型,仿真分析和飞行品质评价验证表明,基于系统误差在线调整人感系统弹性系数,能够降低舵机速率饱和的程度,改善飞行品质,有效抑制舵机速率饱和引起的Ⅱ型PIO。

Abstract: Modern fly-by-wire airframes are often designed to have relaxed static stability and side-stick control, making Pilot-Induced Oscillation (PIO) caused by actuator rate saturation as an important factor affecting flight qualities. In this paper, an active side-stick is designed as a means to alleviate pilot-induced oscillations due to actuator rate saturation. The stiffness of the active side-stick is changed with the actuator rate saturation, so as to mitigate the rate saturation. Based on the pilot-aircraft closed-loop system model with active side-stick, the simulation analysis and evaluation results show that the active side-stick to change the stiffness of the feel system can reduce the degree of saturation, improve flying qualities, and prevent category Ⅱ PIO due to actuator rate saturation effectively.

Key words: feel system, feel system, pilot-induced oscillations, pilot-induced oscillations, category Ⅱ PIO prevention, category Ⅱ PIO prevention, actuator rate saturation, actuator rate saturation, active side-stick, active side-stick
