Simulation of Three-axes Target Tracking System

三轴跟踪瞄准系统的仿真设计

A three-loop system is constructed for a vector control permanent magnet linear synchronous motor ( PMLSM). In the speed-loop and current-loop, an IP controller and a state feedback controller are used for high accuracy and rapid tracking and to restrain disturbance.

把一矢量控制的永磁直线电机构成一个三环系统，在速度环和电流环内采用IP速度控制器和状态反馈控制器，以实现电机的高精度快速进给，并抑制外部扰动对系统的影响。
