駆動装置
Document Type and Number:
Japanese Patent JP6696382
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce a loss in the entirety of drive apparatus in executing PWM control as the control of an inverter and to suppress deterioration in efficiency when viewed as the entirety of drive zone of a motor.SOLUTION: When executing PWM control as controlling of an inverter, a control device executes the processing of: setting a base effective value and a base advance angle value so as to minimize a current effective value on the basis of a torque instruction to a motor; setting a provisional advance angle value correction amount so as to minimize a loss in an entirety of a drive apparatus than the base advance angle value, setting a correction factor that is inversely proportional to a magnitude of a modulation ratio, and setting a current advance angle value by correcting the base advance angle value by using an advance angle correction amount obtained as a product of the provisional advance angle value correction amount and the correction factor; and setting an effective value correction amount so as to minimize a difference between a torque instruction to the motor and output torque thereof, and setting a current effective value by correcting the base effective value by using the set effective value correction amount.SELECTED DRAWING: Figure 3
