改进的PR控制器对PMSM电流的矢量控制策略
|
摘要
针对比例积分(PI)控制器在同步旋转坐标下对PMSM电流矢量控制方面的不足,结合永磁同步电机(PMSM)数学模型,提出一种在静止坐标下通过改进的比例谐振(PR)控制器对PMSM电流矢量的控制策略.通过双线性变换对改进的PR控制器进行离散化处理.仿真和实验结果表明,在控制器增益参数一致的情况下,该控制策略与PI控制器相比较,电机转速波动量更小,运行更加稳定,不含与电机参数有关的补偿项,结构简单,同时在静止坐标系下,减少了计算的复杂度.
With the combination of the PMSM mathematical model,in stationary coordinates,a current vector control strategy for PMSM based on an improved proportional resonant(PR) regulator is introduced to overcome the shortage of proportional integral(PI) regulator in synchronous rotating coordinates. The discretization of improved PR regulator by bilinear transformation. Simulational and experimental results show,when the two regulators with the same parameters,the speed fluctuation of the control system with improved PR regulator is smaller than the control system with PI regulator,and simple structure because of the control system with PR regulator without voltage compensation,and the computational complexity is reduced in the stationary coordinate.
