  • ELECTRIC VALVE/DOOR, AND CONTROL APPARATUS AND METHOD THEREOF
    Publication number: 20250119084
    Abstract: An electric valve/door, and a control apparatus and method thereof are provided. The electric valve/door includes a control apparatus. The control apparatus includes an alternating current (AC) asynchronous motor, a transmission device, and a valve driver. The valve driver is connected to the AC asynchronous motor. The AC asynchronous motor is connected to the valve/door through the transmission device. The valve driver is configured to collect information of a real-time torque of the AC asynchronous motor or the valve/door during operation, and take a set torque of the valve driver as an input and the real-time torque as a feedback to immediately correct an output torque of the valve driver or a limit value of the output torque by using a proportional-integral-derivative (PID) control algorithm, to meet requirements for response speed and control precision of each stage in opening and closing processes of the valve/door.
