Proportion control system of closed ring with hydraulic and electronic integration

Abstract

The invention discloses a proportion control system of a closed ring with hydraulic and electronic integration, which can solve the problems of automatic control, automatic setting and automatic drawing of pressure curve of a hydraulic pressure-retaining system and solve the problems that the pressure error of the existing control system can not correct error automatically, the high-pressure boosting is hard, the pressure is hard to retain, the pressure decreases quickly, the pressure fluctuate interval can not be set, and the pressure curve can not be drawn precisely. The promotion control system is realized as follows: a control program is edited by computer software; a closed ring controls a system mathematic model, a hardware PLVC and an industrial control machine control system to realize that a simulated hydraulic pressure signal is modulated by a simulated voltage signal, thus realizing automatic drawing of the curve and driving control of an actuating component; the negative feedback of the closed ring is used for automatically eliminating error signals so as to lead the control precision of the system pressure to reach very precise requirements. After combining the model,the proportion control system provides the processes of boosting pressure, retaining pressure, keeping constant pressure and reducing pressure for the product in the model according to time period and realizing precise control and drawing of time and pressure curve diaphragm.
