Title:
SERVO CONTROL METHOD AND APPARATUS FOR DOOR MODULE, ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/088626
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present application are a servo control method and apparatus for a door module, an electronic device and a storage medium. According to the embodiments of the present application, a direct-axis voltage amplitude and a quadrature-axis voltage amplitude of a direct-drive servo motor are calculated and limited to implement the setting of a maximum operation torque of the direct-drive servo motor and implement position loop torque control or speed loop torque control in a closed-loop direct-drive servo drive control process of a door module of a gate, so that when the door module of the gate operates in a door opening or closing state, a small operation torque is provided to prevent the door from strongly impacting a human body and damaging the human body due to excessive torque, and when the door module of the gate is locked at a stop position, a large operation torque is provided to obtain a good door module locking effect at the stop position and prevent the door from being easily opened manually due to low torque, thereby optimizing the user experience.
