弹道修正弹中舵机的控制

The Control of Steeringengine Trajectory Correction

为对弹道修正弹舵机进行控制,实现高速旋转稳定弹丸的二维修正,提出电压调速控制电机的方法。以转台运行模拟弹丸在空气中的飞行,设计出斩波控制电路,并对控制电路和控制算法进行改进,通过改变占空比控制电磁转矩,对电机进行控制。实验结果表明,电压调速控制电机的方法控制准确性、快速性和稳定性好,抗过载能力较好,能够对舵机进行有效控制,为二维弹道修正执行机构的电机调速提供了依据。

For the control of the steering engine of trajectory correction projectile,realization of two-dimensional correction of high-speed rotating stable shells,the method to improve correction accuracy is proposed,by contrelling the motor projectile. By running the turntable to simulate the flight of the shell in the air,two effective programs of correction motor are preposed. A drive circuit is designed and the control circuit and control algorithm are improved. The simulation results showthat this method can control the steering engine. The research provides a basis for two-dimensional trajectory correction actuator to motor speed.
