The paper deals with the structure and drive of the adaptive electro-hydraulic control system and practical verification of the identification and control algorithms. The electro-hydraulic servo system composed of hydraulic cylinder controlled by proportional valves is discussed. The parameters of the adaptive adjuster were determined by means of the results of the current identification of the parametric model. The identification was conducted on the basis of the measurement of the object&s controlling size and the regulated size of the object. The identified model of the object was applied to carry out on-line synthesis of the PID adjuster. The selected problems connected with obtaining the algorithm of adaptive control are presented. A computer program implementing the algorithm with the numerical simulation and the identification of the physical model of the control object is worked out. The aim of the research is to examine the effectiveness of adaptive control method in electro-hydraulic servo systems both theoretically and experimentally.

Paper Title:
Dynamic Modeling and Tracking Control Simulation for Large Electro-Hydraulic Servo System
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.
