Problems solved by technology

[0003] However, during the operation of the closed-loop direct-drive servo drive control system of the existing gates, when the control fan door module performs the operation of opening and closing the door, it is prone to strong impacts such as clamping on the human body, which will cause personal injury, and the gate is in the stop position. When locked, the position cannot be locked well, which further affects the user experience

Abstract

The embodiment of the invention discloses a servo control method and device for a door module, electronic equipment and a storage medium. According to the embodiment of the invention, the direct-axisvoltage amplitude and the quadrature-axis voltage amplitude of a direct-drive servo motor are calculated and limited to realize the setting of the maximum running torque of the direct-drive servo motor and realize position loop torque control or speed loop torque control in the closed-loop direct-drive servo drive control process of a gate door module. Thus, when the gate door module runs in a door opening or closing state, a small running torque is provided so that the door is prevented from strongly impacting a human body and damaging the human body due to overlarge torque; and when the atedoor module is locked at the stop position, a large running torque is provided so that the door module can be well locked at the stop position, the situation in which the door is easily pushed open manually due to small torque is avoided, and the user experience is optimized.

Description

technical field [0001] The embodiments of the present application relate to the technical field of servo control, and in particular to a servo control method, device, electronic equipment and storage medium of a door module. Background technique [0002] At present, gates are installed in many places in people's lives to realize intelligent channel management. The gate is equipped with a servo control board and a direct drive servo motor. The servo control board is used to drive and control the direct drive servo motor to form a closed-loop direct drive servo drive control system. Through the position loop control and speed loop control of the closed-loop direct drive servo drive control system, In order to realize the synchronous control of the locking of the stop position of the fan door module and the operation of the door opening and closing. [0003] However, during the operation of the closed-loop direct-drive servo drive control system of the existing gates, when the...
