A motor control apparatus for an electric vehicle has an AC motor system including a power conversion unit and a motor/generator. The power conversion unit performs conversion between DC power and AC power to drive the motor/generator. The motor control apparatus further includes a decoupling control section configured to perform decoupling control, which restricts interference between system voltage control and motor torque control, by correcting a control state amount of one of the system voltage control and the motor torque control by a control state amount of the other of the system voltage control and the motor torque control.
