Title:
METHOD FOR CONTROLLING MOTOR, AND MOTOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/044300
Kind Code:
A1
Abstract:
In the method for controlling a motor according to an embodiment, a motor is controlled by voltage phase control performed on the basis of a voltage norm command value representing the size of the voltage to be fed to a motor and a voltage phase command value representing the phase of said voltage. In this method for controlling a motor, there is acquired a necessary time needed to calculate, according to a command value calculation model for performing a calculation using a rotation speed parameter relating to the rotation speed of the motor, the final command value of a voltage to be applied to a motor by voltage phase control. The rotation speed parameter is detected and the detected rotation speed parameter is changed on the basis of the necessary time. Then, the final command value is calculated using the changed rotation speed parameter according to the command value computation model.
