Title:
CONTROL METHOD FOR MOTOR SYSTEM, AND CONTROL DEVICE FOR MOTOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/215891
Kind Code:
A1
Abstract:
A control method for a motor system has: a battery; a step-up converter configured so as to step up DC voltage supplied from the battery; an inverter connected to the step-up converter, the inverter performing conversion between direct current and alternating current; and a motor generator connected to the inverter. The control method for a motor system has: a suppression reference determination step for determining a limit power such that the vibration of the terminal voltage on the inverter side of the step-up converter is suppressed, in accordance with the operation point of the motor generator; and a control step for controlling the operation point of the motor generator so that the passing power of the step-up converter does not exceed the power limit.
