Title:
CLOSED-LOOP MOTOR CONTROL SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/232746
Kind Code:
A1
Abstract:
A closed-loop motor control system and method. The system comprises a forward processing module (10), a control object module (20) connected to the forward processing module (10), and a system identification module (30) connected to both the forward processing module (10) and the control object module (20). The forward processing module (10) is used to process, according to a real-time parameter of a motor (40), an excitation signal to be inputted into the motor (40), and send a first signal generated by the processing to the control object module (20). The control object module (20) is used to process the received first signal, use a second signal generated by the processing to excite the motor (40), and measure an actual voltage at both ends of the motor (40). The system identification module (30) is used to detect an error signal generated between a predicted voltage at both ends of the motor (40) and the actual voltage at both ends of the motor (40), use the error signal to determine a real-time parameter of the motor (40), and feed the determined real-time parameter back to the forward processing module (10). The closed-loop motor control system and method perform parameter tracking and feedback control on the motor, thereby ensuring operational stability of the motor.
