Abstract: According to the feature of electro-hydraulic system and the requirements of closed-loop pressure control, a new type of pressure controller which adopts digital control and fuzzy self-turning PID control algorithm is presented in this paper. During the field experiment, the controller has higher precision, better stability and easier operability than analog closed-loop pressure control. It has better response speed and control precision compared with simple PID algorithm and fuzzy algorithm, moreover, it satisfies technical requirements of pressure control.
