Abstract:In order to meet the requirements of dynamic response and position error, the simulation model was built based on AMESim with graphical interface for the electro-hydraulic position control system, which dynamic characters were simulated,analyzed and optimized. The results show that through bringing speed signal into the closed loop control system to compensate by AMESim, under the premise of satisfying stability of the system, the dynamic respond is speeded up, the dynamic position error is reduced.
