Abstract

The purpose of this study is to develop a control scheme for the hydraulic proportional system using PID function on Mitsubishi PLC Q series which can rapidly control the pressure in a hydraulic cylinder with very short stroke. The mathematical model of the control system is established according to the principle of the electrohydraulic system. Considering the above mentioned characteristics, simulation of the system modelling will be established to know the system response. In order to improve the control precision of the hydraulic hot-press system, the Mitsubishi PID controller are designed by selecting appropriate tuning parameters. Their control performances are analyzed in time domain respectively. The variation of PID controller configuration will be conduct to know the better model for this system controller. The validity of the proposed control scheme is confirmed through the experiments to verify the rationality of the theoretical model. The results show that the Mitsubishi PID and the ideal PID give the same result for the tuning parameter resulted from simulation. And also the experiment give the better stability in the 3 different pressure set value that conduct by author.
