Abstract
In conventional “flow control valve and travel switch” control strategy, relative height difference between multiple cylinders only reach accuracy of centimetre grade, which can’t meet synchronous control accuracy requirements of many engineering. In order to improve multiple cylinders synchronous accuracy of the hydraulic lifting system, this paper takes a hydraulic lifting system as basis, which studies PID closed loop control system using electro-hydraulic proportional valve and high-precision displacement accuracy sensor, and the synchronous accuracy of 4 cylinders hydraulic lifting system is improved to millimetre grade.
