Abstract
A control apparatus for a motor generator that is connected to an internal combustion engine. The control apparatus estimates an estimated torque pulsation that is an estimation value of torque pulsation of the internal combustion engine. The control apparatus controls the motor generator to reduce generated power and suppress decrease in a rotation speed of the internal combustion engine, when a negative torque that obstructs rotation of the internal combustion engine is generated in the estimated torque pulsation of the internal combustion engine.
