摘　　要：航迹仪是一种对精度要求极高的导航标绘设备,其工作过程中较大的噪音振动,严重影响了标绘精度.分析了产生振动噪音的原因,针对步进电机在低速条件下易产生低频振动这一突出问题,给出了增加细分驱动控制的改进方案.通过对步进电机及其细分驱动部分的理论推导,建立了相关模型并对其进行了仿真分析,论证了方案的可行性.The track plotter system is a kind of high precision navigation plotting equipment. Large vibration and noise have seriously affected the accuracy of plot. The cause by the vibration and noise is analyzed, and an improvement scheme is given by increasing the subdivision driver of step motor which usually produces the low-frequency vibration. Through the theoretical derivation of the step motor and its subdivision part, a model is established and the simulation is made to demonstrate the feasibility of the project.
