马格努斯效应对旋转弹自动驾驶仪影响的研究

Research on the Effect of Magnus Effects on Rolling Missile Autopilot

为了分析马格努斯力矩对单通道旋转弹自动驾驶仪的影响,在准弹体系下建立了旋转弹加速度反馈自动驾驶仪模型。观察了不同马格努斯力矩对自动驾驶仪的影响,并与速率陀螺反馈自动驾驶仪进行了对比。仿真结果表明了该建模分析方法的正确性,并证明了加速度反馈相对速率反馈能够有效降低马格努斯力矩对旋转导弹的干扰作用。

To study the effect of Magnus effects on rolling missile autopilot, an acceleration feedback autopilot is designed in quasi-body coordinate. The effect of different amount of Magnus affecting rolling missile autopilot is studied. Comparative analysis is made between the acceleration feedback autopilot and gyro feedback autopilot. Simulation indicates that the method of building the acceleration feedback auto-pilot is correct and also proves that the acceleration feedback autopilot is more effective than gyro feed-back autopilot in reducing the interference effect of Magnus effects on rolling missile autopilot.
