Controller of rotary electric machine

Abstract

To provide a controller of a rotary electric machine which can prevent the vibration torque component to be outputted by the rotary electric machine from being upper-limited by the maximum output torque of the rotary electric machine. A controller of a rotary electric machine decreases an amplitude of the vibration torque command value so that a vibration maximum value obtained by adding an amplitude of a vibration torque command value to a basic torque command value becomes less than or equal to an upper limit command value; and calculates a value obtained by upper-limiting an addition torque command value, which is obtained by adding the vibration torque command value to the basic torque command value, by the upper limit command value, as a final torque command value.
