| 摘 要： | 提出了基于DSP的三相混合式步进电机电压空间矢量SVPWM控制方法。通过对三相步进电机旋转磁场的空间电流矢量合成以及Clarke、Park变换,使绕组中电流在细分控制下得到了较好的电流正弦波形,实现恒转矩控制。实验结果表明,SVPWM控制系统极大的降低了步进电机低频振荡现象,改善了高速运行时的力矩特性。

| Abstract: | Proposed SVPWM control system based on DSP of 3 phase hybrid stepping motor, obtained a round rotating magnetic in motor. Through Clarke Park and their reverse transformation, current is closed, which made the current in each phase similar to sine wave, we can get constant torque control. At last, the result of experiment approved that SVPWM technology reduced oscillation of stepping motor at low frequency and improved the torque characteristic at high speed. |
