摘要：在工业数控加工制造中，常常要求PMSM位置伺服控制系统具有高速平稳、时间精确的定位性能。针对传统三闭环PI伺服位置控制系统通常难以直接满足高速平稳高精度定位的生产要求，克服传统控制中存在的不匹配动态响应影响，提出了一种新型的基于系统模型的新型前馈控制结构，与高速运动轨迹规划配合，实现位置伺服系统的时间和精度无偏差的高速平稳跟踪定位功能。最后通过仿真实验验证了该方法的有效性和对象参数适应性。

Abstract: In industrial CNC machining manufacturing, often require PMSM position servo control system with highspeed smooth, accurate positioning accuracy.A new type of feedforward control system based on system model was proposed to overcome the influence of the mismatch dynamic response in traditional control,and highspeed trajectory planning with the realization of the position of the servo system time and accuracy without deviation of the highspeed smooth tracking and positioning function.Finally, the validity of the method and the adaptability of the object parameters were verified by simulation experiments.
