摘要

针对固定鸭舵弹道修正组件在旋转稳定榴弹中的应用问题，介绍了固定鸭舵的结构组成及工作原理。在分析双转式永磁无刷直流电机控制系统组成的基础上，建立了双转永磁无刷直流电机的数学模型，提出了一种电流、转速双闭环单通道滚转控制策略。通过双轴仿真测试转台，对电机控制效果及模拟飞行进行了模拟实验与测试，结果表明：该方式控制效果较好，控制精度较高，能够满足弹药简易制导的要求。%According to the application problem of the fixed canard trajectory correction kit technology in dual-spin stabilized projectiles,this article introduces the structure and working principle of the fixed canard kit. Base on the analysis of the control system of dual-rotor permanent magnet brushless motor,the mathematical model is established. And then the single channel control strategy which includes inner current-loop and the outer speed-loop is presented. The motor control effects,and the simulated flight simulation experiment is carried out using biaxial simulation test turntable at a high speed. The final testing data indicates that the control system can achieve preferable performance and high control precision,and suit the requirements of simple guidance.
