摘要
为了能使双转子永磁同步电机(Anti-rotary permanent synchronous motor,Anti-rotary PMSM)能在负载变化情况下仍能保持同步运行,提出一种空间矢量调制下的速度控制方法。在原理分析的基础上,对双转子永磁同步电机的定子磁链和转矩进行分别计算,从而实现电机的有效控制。同时,为了验证本文所提方案的有效性,利用Matlab对方案进行了仿真研究。仿真结果表明,本文所提的控制方案可以有效控制好双转子同步旋转的问题,说明了该控制方案是有效的。
In order to keep the anti-rotary permanent magnet synchronous motor(Anti-rotary PMSM)runs at the same speed under load changes,a speed control method based on space vector modulation was proposed.On the basis of the principle analysis,the stator flux linkage and the torque of the anti-rotary PMSM were calculated separately.At the same time,in order to verify the effectiveness of the proposed scheme,the simulation of the scheme was carried out based on Matlab.The simulation results show that the proposed control scheme can effectively control the synchronous rotation of the two rotors,and the results of the control scheme show the control scheme is effective.
