摘　　要：当前采用大展弦比的垂直发射导弹,由于转弯段大攻角的气动耦合、弹翼结构不可避免的扭转误差、发动机推力偏斜以及燃气舵片等影响,使得导弹倾斜通道存在较宽范围的复杂干扰力矩。通过对倾斜通道的干扰力矩进行分析,提出了一种易于工程实现的抗宽范围复杂干扰力矩的控制方法,采用自适应限幅与模型参考控制相结合的控制方案,可以有效抑制倾斜通道的复杂干扰力矩。经过仿真试验与飞行试验验证,实现了垂直发射导弹的倾斜稳定控制,满足了武器系统的设计要求。At present,vertical launch missile with high aspect ratio,but due to the aerodynamic coupling of the large angle of attack during the turning section,the inevitable torsion error of the wing structure,the deflection of the engine thrust and the influence of the gas vane flake,the inclined channel of the missile has a wide rangecomplex interference moment.This paper analyzes the interference moment of the inclined channel,and proposes a control method which is easy to implement in engineering against a wide range complex interference moment.The control scheme combines adaptive limiting and model reference control can effectively suppress the complex interference moment of the inclined channel.After verification by simulation experiment and flight test,the tilt and stability control of the vertical launch missile are achieved and meets the design requirements of the weapon system.
