摘要:
A rotary electric machine control system includes a control device that controls a rotary electric machine. When there is a current phase at which a reluctance torque is maximum between a first current phase (Θ1) of a first current vector (I
1 ) on which current pulses have not been superimposed yet and a second current phase (Θ2) of a second current vector (I
2 ) obtained by increasing a d-axis current and reducing a q-axis current, the control device sets an intermediate current vector (Im) having an intermediate phase (Θm) between the first and second current phases (Θ1, Θ2). The intermediate current vector (Im) is set so as to be larger than an imaginary current vector (Ima) at the intermediate phase (Θm) in the case where a vector locus is varied in a straight line from the first current vector (I
1 ) to the second current vector (I
2 ). The current pulses are generated by changing the current vector in order of I
1 , Im and I
2 and returning the current vector in order of Im and I
1 .
