Title:
モータの制御方法、及び、モータ制御装置
Document Type and Number:
Japanese Patent JP7205660
Kind Code:
B2
Abstract:
A motor control method for controlling a motor by using an applied AC voltage converted from a DC voltage with an inverter driven by a PWM control, the motor control method includes: calculating a voltage command value for the inverter in order to achieve a desired torque output in the motor; calculating a compensation gain configured to maintain a linear relation between the voltage command value and the applied AC voltage according to a modulation factor indicating a ratio of the applied AC voltage to the DC voltage before and after a conversion in the inverter; limiting the compensation gain using an upper limit value; calculating a compensation voltage command value by multiplying the voltage command value by the limited compensation gain; and applying the applied AC voltage to the motor by driving the inverter using the compensation voltage command value; wherein the upper limit value is set so that the upper limit value become smaller when the modulation factor changes significantly.
