In order to improve the accuracy of dual axis synchronous control of lifting equipment,this article introduces closed-loop feedback technology and conducts research on intelligent synchronous hydraulic automatic lifting control technology.This study introduces moving average filtering technology for signal preprocessing.The closed-loop feedback control system takes the output as a part of the input,uses PID based adaptive control technology and combines the output of the controller to dynamically adjust the intelligent synchronous hydraulic lifting according to the synchronization error.The experimental results demonstrate that the application of the designed automatic lifting control method can ensure that the dual axis lifting displacement trend of the equipment is consistent with the height,thereby achieving the expected control effect.
