摘要
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电机的定位检测控制是关键。依据二维修正固定鸭舵工作原理及对永磁同步电机控制方法的研究,采用霍尔传感器进行位置检测的方式实现舵机的修正控制。通过在模拟样机安装霍尔传感器,采用改进的六短时脉冲定位技术,提高舵机的位置检测精度和测速精确性。实验结果表明,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。
To realize the high-speed spinning projectile trajectory correction, the correction of steering gear reduction spinning and servo system of permanent magnet motor positioning control testing are critical. Based on the two-dimensional fixed duck rudder work principle and control methods research of the permanent magnet synchronous motor, the way of steering gear system location correction control is detected by hall sensor. Through the installation of hall sensor in the simulation prototype, the position detection precision of the steering gear and speed measuring precision is improved by the improved six short pulse positioning technology. Experimental results show that the steering gear control system structure is sim- ple 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 re search.
