Abstract
In this paper, electro-hydraulic proportional control technology is used in speed control by a lead cathode walking-beam conveyer in order to ensure the accuracy of conveyor speed control. In simulation analysis, PID correction based on MATLAB software is used for the electro-hydraulic proportional control system. According to the results of simulation, PID correction is used to correct the system. And, trial and error are used to get suitable PID parameters. Simulation results show that: when there are small changes in load inertia, the system should have better indicators in time domain and frequency domain. It can deduce the requirements of lead cathode walking-beam conveyer speed control.
