【摘要】 电磁转矩控制是永磁同步电动机控制中的关键环节。为简化转矩控制方案,本文从永磁同步电动机电磁转矩与三相电流幅值之间的关系出发,研究了一种简易的电流控制方法。该方法仅用一个电流幅值控制器,可以实现三相电流以及电磁转矩的间接控制。同时,该方案不需复杂的坐标变换,不但可以简化系统控制结构,而且可提高系统的实时性。实验结果表明,以上方案是可行的.更多还原

【Abstract】 Control of the electromagnetic torque is the key to the servo systems of the permanent magnet synchronuous motors(PMSM).A simplified strategy of current control is proposed according to the relationship between the torque and the amplitude of three phase current.This strategy can control three phase current and the torque indirectly with only one current controller.In addition,it can not only simplify the control structure,but also improve the real-timing of the servo systems since it does not need complicate coordinate transformations. Experiment results demonstrate that the proposed stratrgy is feasible.更多还原
