Abstract: A control apparatus calculates a total loss change amount that is a power loss change amount of a motor control system including respective power loss change amounts of a converter, an inverter, and a motor of the motor control system. Based on the total loss change amount, during a correction-allowed period that is a period during which square wave control is performed, the control apparatus performs correction to decrease a current output voltage command value of the converter when the current output voltage command value is determined to be greater than the output voltage of the converter at which actual total power loss change amount becomes minimum. When the current output voltage command value is determined to be less than the output voltage of the converter at which actual total power loss change amount becomes minimum, the control apparatus performs correction to increase the current output voltage command value.

Abstract: Upon determining that the absolute value of an electrical angular speed of a motor-generator is smaller than or equal to a threshold value, a control apparatus compensates a current detected by a U-phase current sensor based on a temperature detected by a U-phase temperature sensor and compensates a current detected by a V-phase current sensor based on an estimated temperature of a V-phase current sensor. On the other hand, upon determining that the absolute value of the electrical angular speed is larger than the threshold value, the control apparatus compensates the currents detected by the U-phase and V-phase current sensors based on temperature detected by the U-phase temperature sensor.

Abstract: In a control device, a control unit controls at least one switching element of a converter to increase a voltage supplied from a battery, thus outputting the increased voltage to a rotating electrical machine. The rotating electrical machine is capable of driving, based on the increased voltage output from the converter, an internal combustion engine, and capable of charging the battery based on torque supplied from the internal combustion engine. A limit unit limits, based on a change of an available maximum output of the internal, combustion engine, the increased voltage output from the converter to be equal to or lower than a predetermined upper limit.

Abstract: A control system includes a boost-buck converter, a control apparatus and a voltage sensor. The boost-buck converter is provided between a battery and a motor-generator. The control apparatus controls the boost-buck converter. The voltage sensor outputs a sensor output value of a system voltage supplied to the motor. The control apparatus calculates a current stagnation continuation period based on the sensor output value of the voltage sensor and corrects a duty ratio of the boost-buck converter in accordance with a calculation value of the continuation period. The continuation period includes a predetermined time point, at which current stagnation is assumed to be generated. The current stagnation indicates that at least a reactor current stagnates. In the continuation period, a system voltage-related voltage continues to have a voltage difference of the same polarity side relative to a reference voltage.
