Simulation Analysis of Proportional Valve Controlled Cylinder Hydraulic System Based on AMESim

Focusing on the performance of proportional valve controlled cylinder, by using AMESim simulation software, dynamic performance of the system has been simulated. Starting by the control strategy, using Genetic Algorithm,the PID parameters which can affect the hydraulic cylinder position accuracy will be optimized. The simulation results show that the optimized parameters can improve system performance, and achieved excellent results.
