摘要
永磁同步电机(PMSM)转速调节大多采用比例积分(PI)控制,由于系统的初始误差值较大,其存在调速范围小、快速性与超调量不能兼顾的问题。将跟踪微分器用于PMSM转速调节系统中,对参考输入安排光滑的过渡过程,降低系统的初始误差,通过增大PI调节参数来保持转速响应的快速性,实现了转速响应快速超调小,增强了系统的鲁棒性和适应性。仿真实验结果验证了此种方法的优越性。
The speed control of permanent magnet synchronous motor （PMSM） mainly applies the propor- tional integral （PI） control algorithm, however,due to the systemrs big original error,it can not take into ac- count of small speed range, rapidity and overshoot problems. A new algorithm was proposed for the speed control of PMSM which adds tracking-differentiator in the control system, arranging the smooth transition course for the reference input, reducing the system＇s original error, by increasing the PI controller parameters, it can maintain the rapidity of the speed response and can turn down speed response rapidity with small over- shoot and improve the robustness and adaptability of the system. Simulation results prove the proposed algo- rithmts superiority.
