Abstract: A control device for a motor drive system including an AC motor having a magnet in a rotor, a converter, and an inverter generates a step-up command value for the converter based on a torque command value for the AC motor. The control device determines whether or not to carry out field-weakening control for increasing a current in a direction weakening force of a magnet that is supplied from the inverter to the AC motor, based on the step-up command value and a state of drive of the AC motor. When field-weakening control should be carried out and when an absolute value of the torque command value is smaller than a threshold value, the control device further increases the generated step-up command value. By doing so, an amount of a field-weakening current can be decreased and therefore efficiency of the motor drive system can be improved.

Abstract: When a DC/DC converter switches between a primary voltage control mode, a secondary voltage control mode, and a current limiting mode as operation modes, an I-term resetting processor outputs an I term depending on the duty ratio in the operation mode before being switched to a PID processor. The PID processor performs a PID control process based on the input I term. A drive duty ratio setter outputs a drive duty ratio immediately after the control mode switching, which is substantially equal to the duty ratio in the operation mode before being switched. As a result, the duty ratios in the operation mode before being switched and the operation mode after being switched are made continuous with respect to each other.

Abstract: A motor controller for an axial-gap motor permits a reduced size of the entire system of including a drive circuit and a power source of the motor, reduced cost, and higher reliability to be achieved by controlling the energization mode of the motor. The motor controller has a torque command determiner which inputs a first DC voltage to a first inverter at least either when a rotor is at a halt or when the number of revolutions of the rotor is a predetermined number of revolutions or less, supplies a field axis current for changing the magnetic flux of a field of the rotor to a first stator from the first inverter such that the amount of energization is temporally changed, converts an induced voltage developed in a second stator by the supplied field axis current into a second DC voltage by a second inverter, and outputs the second DC voltage, thereby charging a second battery.
