Fuzzy PID Control for Valve-Controlled Cylinder Hydraulic System

Abstract:

A valve-controlled cylinder hydraulic system is used widely in engineering. The principle of the valve-controlled cylinder hydraulic system is presented. The fuzzy PID controller of valve-controlled cylinder hydraulic system is designed, and the simulation model is built. Based on the model, simulation analysis is carried out. The results show that the PID controller parameters can change with the variations of control error and control-error change rate according to fuzzy reasoning, the response error of valve-controlled cylinder is kept in a range of -0.06～0.1cm, and the required control accuracy can be obtained.
