摘要
在传统电压空间矢量SVPWM控制基础上进行了改造,提出了一种新颖的空间矢量电流控制的策略以抑制转矩脉动,使三相定子电流输出为接近理想的矩形波;并在MATLAB/Simulink环境下,比较了几种常用的控制方式对抑制转矩脉动的效果;仿真结果表明,提出的控制策略能有效地抑制转矩脉动,提高系统性能。
A novel space-vector current control strategy to minimize the torque ripples was presented in this paper,based on conventional SVPWM control method. Then more rectangular phase currents was obtained. 4 kinds of control results were compared based on MATLAB / Simulink. The simulation results prove the proposed modulation method can effectively restrain the torque ripple and improve system performance.
