Abstract:
1. A motor control apparatus for an electric vehicle comprising: voltage conversion means, connected between a DC power source and a system power line, for supplying a DC system voltage to the system power line by converting a voltage of the DC power source; an AC motor system including power conversion means and a motor/generator, the power conversion means being connected to the system power line and configured to perform conversion between DC power and AC power, and the motor/generator being driven by the power conversion means; voltage control means configured to perform voltage control, so that the system voltage attains a target voltage; torque control means configured to perform torque control, which controls the power conversion means, and adjusts a phase of an AC voltage supplied to the motor/generator so that an output torque of the motor/generator attains a target torque; and decoupling control means configured to perform decoupling control, which restricts interference between the voltage control and the torque control by correcting a control state amount of one of the voltage control and the torque control by a control state amount of an other of the voltage control and the torque control.
