Abstract
A control method for a motor system, the motor system having a battery; a boost converter configured to increase DC voltage supplied by the battery; an inverter connected to the boost converter and configured to execute a conversion between DC power and AC power; and a motor generator connected to the inverter. The control method comprising: a limiting power determination step of determining a limiting power in response to an operating point of the motor generator such that an oscillation of a terminal voltage of the boost converter at a side of the inverter is suppressed; and a controlling step of controlling the operating point of the motor generator such that a passing power of the boost converter does not exceed the limiting power.
