针对战斗类飞机非对称投弹和非对称挂载这类情况,分析了投弹时横向扰动及纵向机动时横向耦合的机理,描述了其对飞行安全的威胁;通过引入所投弹质量、位置以及飞机法向过载,设计了非对称投弹/非对称挂载补偿控制律。仿真验证结果表明:该补偿控制律可消除上述两种情况下的横向扰动,有助于非对称投弹时飞机状态的保持,更重要的是提高了非对称挂载情况下着陆的安全性。
Aiming at the asymmetric loading and asymmetric loading of combat aircraft, this paper analyzes the mechanism of transverse disturbance and longitudinal coupling during longitudinal maneuvering, and describes its threat to flight safety. By introducing the quality, location and aircraft method To overload, designed asymmetric bombing / asymmetric mount compensation control law. The simulation results show that the compensation control law can eliminate the lateral disturbance in the above two cases, and it is helpful to maintain the state of the aircraft during the asymmetric bombing and, more importantly, to improve the safety of the landing under the asymmetric loading.
