Method and apparatus for controlling operation of brushless winch motor

A method for controlling operation of a brushless winch motor, the method comprising:

• obtaining historical operating data of the winch motor to build an operating model of the winch motor;
• obtaining a basic parameter of the winch motor upon startup of the winch motor and outputting first predicted operating data of the winch motor based on the basic parameter of the winch motor and the operating model of the winch motor;
• obtaining an actual first-moment operating parameter of the winch motor, and comparing the actual first-moment operating parameter of the winch motor with a predicted first-moment operating parameter in the first predicted operating data of the winch motor to obtain a first offset;
• outputting a first feedback parameter based on the first offset and a motor model, and adjusting operation of the winch motor based on the first feedback parameter;
• obtaining an actual second-moment operating parameter of the adjusted winch motor, and comparing the actual second-moment operating parameter of the winch motor with a predicted second-moment operating parameter in the first predicted operating data of the winch motor to obtain a second offset;
• correcting the operating model of the winch motor based on the second offset, outputting predicted second-moment operating data based on the corrected operating model of the winch motor, and adjusting operation of the winch motor based on a difference between an actual operating parameter of the adjusted winch motor and the predicted second-moment operating data as a second feedback parameter;
• and
• obtaining a real-time rope length during operating of the winch motor and controlling the winch motor to stop when the real-time rope length reaches a preset rope length.
