摘要
研究了一种变参数PI控制器,用于永磁同步电动机(PMSM)矢量控制系统中的速度控制。该控制器根据输入误差的大小,通过非线性函数在线改变比例增益和积分增益,以获得满意的控制性能。仿真研究结果表明,采用该方案的系统具有响应速度快、动静态性能好和鲁棒性强的特点。实验结果证明了该方案的正确性和可行性。
A variable argument PI controller used for speed control in the vector control system of permanent magnet synchronous motor (PMSM) is put forward.This controller could have good performance,in which the nonlinear functions are employed to change the proportional gain and integral gain according to the input error.Simulation study of the new scheme has been done.The results show that the method has fast reaction, good dynamic and static performance and strong robustness.And the experiment verifies the feasibility and correctness of the scheme.
