Simulation of Three Loop AC Servo System for Motion Control Based on MATLAB

针对交流伺服运动控制系统,在PMSM伺服系统电流环和速度环的基础上,进行位置环设计,保证伺服电机位置跟踪的精确性。同时,利用S曲线加减速算法进行速度规划,减小电机在加减速过程中的机械振动,以保证控制系统的稳定性和快速性。在MATLAB/Simulink中建立伺服系统仿真模型,仿真结果表明,上述方法能使系统具有很好的精确性、快速性和抗扰动性。

For the AC servo motion control system,a position loop is designed in this paper to ensure the accuracy of the servo motor position tracking,on the basis of the current loop and speed loop of PMSM servo system.At the same time,the s-shape acceleration / deceleration（acc / dec） algorithm will be used for speed planning,reducing the mechanical vibration of the motor in the process of acc / dec to ensure stability and rapidity.And the simulation model of position servo system was constructed in MATLAB / Simulink module.
