Dynamic Modeling and Tracking Control Simulation for Large Electro-Hydraulic Servo System

Article Preview

Abstract:

The co-simulation method of one large electro-hydraulic servo system based on software interface is proposed in this paper. The rigid-flexible-coupling dynamic model of the electro-hydraulic servo mechanism was built through data exchange of SolidWorks, ANSYS and ADAMS, the hydraulic system model and control system framework was built by EASY5 environment, the controller was built by Simulink. The integration of simulation models for the large electro-hydraulic servo system was realized by software interfaces. In view of the poor operation conditions, the high requirement of control precision and real-time characteristics, adaptive fuzzy sliding mode control strategy was applied to position tracking control of the servo system. Simulation results verified the effectiveness of this method.
