PROBLEM TO BE SOLVED: To provide a control device for a multiple winding rotary electric machine that can enhance responsibility of a current control system.SOLUTION: A control device has a speed calculator 42, each voltage deviation calculator 41, 51, 61, 71, each speed interference voltage calculator 44, 54, 64, 74, and each voltage compensator 45, 55, 65, 75. Each voltage deviation calculator 41, 51, 61, 71 calculates each voltage deviation &Dgr;Vd1,&Dgr;Vd2,&Dgr;Vq1,&Dgr;Vq2 for controlling current flowing through each winding group to instruction current. A speed calculator 42 executes differential calculation on a detection value of an electrical angle &thetas; to calculate an electrical angle speed ω. Each speed interference voltage calculator 44, 54, 64, 74 calculates each speed interference voltage on the basis of the electrical angle speed ω. Each voltage compensator 45, 55, 65, 75 compensates each voltage deviation &Dgr;Vd1,&Dgr;Vd2,&Dgr;Vq1,&Dgr;Vq2 with each speed interference voltage. Here, the electrical angle speed ω used to calculate each speed interference voltage is not subjected to low pass filter processing. |
