Title:
METHOD, DEVICE, AND SYSTEM FOR CONTROLLING MOTOR BY USING DIGITAL PID CONTROL UNIT CAPABLE OF SETTING GAIN
Document Type and Number:
WIPO Patent Application WO/2023/068487
Kind Code:
A1
Abstract:
A motor control system capable of setting gain, according to one embodiment of the present invention, comprises: a motor control unit, which performs a PID operation so as to generate and output a pulse width modulation (PWM) signal; a motor driving unit for generating and outputting a motor driving signal on the basis of the PWM signal; and a motor unit driven on the basis of the motor driving signal, wherein the motor control unit generates, as an error value, the difference between an inputted reference signal and a feedback signal that has been fed back from the motor, selects a preset gain value corresponding to the generated error value, and can perform the PID operation by using the gain value.
