    • PROBLEM TO BE SOLVED: To more appropriately switch motor control between rotating magnetic field control in which a rotor is rotationally driven by a rotating magnetic field and fixed magnetic field control in which the rotation of the rotor is limited by a fixed magnetic field. SOLUTION: When motor control is switched from rotating magnetic field control to fixed magnetic field control in a vehicle, the following steps are carried out to control the motor. Using the phase currents Id2t, Iq2t of the rotating d axis and the rotating q axis in rotating magnetic field control, current commands Id2t*, Iq2t* and voltage commands Vd2t*, Vq2t* are set (S510, S520). The set current commands Id2t*, Iq2t* of the rotating d axis and the rotating q axis are replaced with the current commands Id2lo*, Iq2lo* of the fixed d axis and the fixed q axis in fixed magnetic field control (S540). The voltage commands Vd2t*, Vq2t* of the rotating d axis and the rotating q axis are replaced with the voltage commands Vd2lo*, Vq2lo* of the fixed d axis and the fixed q axis (S550, S560).

    • 要解决的问题:为了更适当地在转子通过旋转磁场旋转驱动的旋转磁场控制和转子的旋转被固定的磁场限制的固定磁场控制之间切换电动机控制 。

      解决方案:当电机控制从车辆的旋转磁场控制切换到固定磁场控制时,执行以下步骤来控制电机。 在旋转磁场控制中使用旋转d轴的相电流Id2t,Iq2t和旋转q轴,设定电流指令Id2t *,Iq2t *和电压指令Vd2t *,Vq2t *(S510,S520)。 在固定磁场控制中,固定d轴和固定q轴的电流指令Id2lo *,Iq2lo *代替旋转d轴和旋转q轴的设定电流指令Id2t *,Iq2t *(S540)。 旋转d轴和旋转q轴的电压指令Vd2t *,Vq2t *被固定d轴和固定q轴的电压指令Vd2lo *,Vq2lo *替代(S550,S560)。 版权所有(C)2009,JPO&INPIT
