Research on Rolling Control of Fixed Canard Base on Dual-Rotor DC Motor

提出一种基于双转式直流电机作为控制执行机构的固定鸭舵弹道修正方案,即弹丸飞行过程中存在弹道偏差时,通过控制双转式直流电机的转速控制固定鸭舵修正舵面相对大地的位置,以消除弹道偏差,提高落点精度。基于双转式直流电机的原理,设计了相应的控制电路及控制算法,通过半实物仿真实验验证了双转式直流电机的控制效果。

correction projectile＇ For traditional Spin-stabilitied projectile＇ s the problem of poor precision, a trajectory scheme based on fixed canard is proposed. When the biases of trajectory exists during the s flight, magnetic brake as control mechanism, controlling the position of canard, eliminating the bias of trajectory and advancing the accuracy of impact point. The paper based on the theory of magnetic brake, designed relevant control circuits and algorithm, tested and verified the control result of magnetic brake employing the semi-physical simulation the shooting range experiment .
