Abstract

A proportional regulating valve is a hydraulic control valve that allows the output of the output oil parameter (pressure) to vary proportionally to the input electrical signal parameter (current or voltage). Due to the non-linearity of the regulating valve system and the problem of poor response characteristics, this paper studies the performance optimization problem of the system. In order to make the system work steadily, by adding iterative learning controller of Proportion-Integral-Derivative type, the system hydraulic pressure increases with the number of iterations gradually approaching the actual pressure required by the load. The simulation results show that the digital regulating valve based on Proportion-IntegralDerivative control law iterative learning control has fast response speed, high control precision and stable operation. So it can be used as an effective solution to achieve high-performance digital regulating valve.
