高速旋转弹丸弹道修正的实现,修正舵机的减旋和舵机系统中永磁同步电机的控制是关键。介绍修正弹舵机结构和组成,依据二维修正固定鸭舵工作原理和舵机修正过程中所受力矩分析,提出采用脉宽调制技术实现电机的双闭环控制系统。通过在模拟样机平台进行舵机停止角度的实验表明,该舵机控制系统结构简单,定位精度理想且在高速旋转状态下系统稳定性好、可靠性高,为后续高旋弹二维弹道修正舵机控制系统的研究提供了实验依据。

The high-speed spinning projectile revises steering gear reduction spinning and servo system of permanent magnet motor positioning control testing.Introduce correct projectile structure and composition of the steering gear.According to the working principle of the two-dimensional modified fixed duck steering and steering gear fixed by torque in the process of analysis. Pulse width modulation technique is proposed for motor double closed loop control system.Through prototype platform for steering gear to stop angles the results show that the steering gear control system structure is simple with the ideal positioning accuracy.And under the condition of high speed rotating system,it has good stability and high reliability,which provides experimental basis for subsequent spiral spring two-dimensional trajectory correction on steering gear control system research.
