针对飞机在低动压飞行(如着舰)时处于阻力曲线反区所采用的Frontside操纵和Backside操纵方式,分别从指令控制、风扰抑制、执行机构影响三种情况对两种操纵策略的性能进行了仿真比较,得出相关结论,并分析了其内在物理原因。研究结果表明,Backside操纵性能优于Frontside操纵,具有响应快、超调小、无初始负调、抗风鲁棒性强,以及俯仰角、迎角和升降舵变化小等特点,但同时速度和推力变化大,且执行机构相位滞后对Backside操纵性能影响较大。
Aiming at the Frontside control and Backside control mode adopted by the aircraft in the anti-zone of the drag curve during the low-dynamic-pressure flight (such as landing), the performance of the two control strategies from the command control, wind disturbance suppression and actuator influence The simulation results are compared, the relevant conclusions are drawn and the intrinsic physical reasons are analyzed. The results show that the Backside maneuver performance is better than that of the Frontside maneuver, which has the characteristics of fast response, small overshoot, no initial negative tone, strong wind resistance, small change of pitch angle, angle of attack and elevator, but the speed and thrust Large changes, and the actuator lag phase of Backside manipulation performance greater impact.
