【正文】 itable trend of development of hydraulic technology. In this paper, the research object is the lifting equipment of electrolytic lead residual anode washing production line, and it adopts electrohydraulic digital control to achieve speed control of lifting equipment. Firstly, this paper analyses the types, strengths and weaknesses of existing digital valves, the structure and working principle of lifting equipment. It selects hydraulic motor as implementation ponents of hydraulic control system, and selects digital direction flow valve which has pressure pensation device to control speed and rotation direction of hydraulic motor. It can realize design of electrohydraulic digital speed control system by the application of velocity feedback and microputer control. D/A signal conversion of this system is controlled by stepper motor of digital valve. This control manner leaves out D/A conversion device, and simplifies the hydraulic control system structure. Then it establishes the mathematical model of the electrohydraulic digital speed control system, adopts the characteristic equation roots method and frequency domain analysis to determine the relative stability of the closedloop system, and makes a simulation analysis of the control system by the application of MATLAB/Simulink software. Based on the simulation analysis, it adds PID correction link in order to ensure the stability and fast of speed control of the lifting equipment, to achieve accurate speed controlThe analysis showed that adopt electrohydraulic digital control technology in speed control system of the lifting equipment is feasible. It can ensure stability of lifting speed, and speed response is fast. Theoretically, it can realize zero speed error, provide a better control method for speed control system of the lifting equipment of electrolytic lead residual anode washing production line, and lay a theoretical foundation for improving production efficiency.
