Abstract

The structure and operating principle of Electro-hydraulic servo system were described, and the Co-Simulation based on AMESim and Matlab was performed. Furthermore, aiming at the problem that construction of an accurate model of an Electro-hydraulic servo system based on traditional linear methods remains a difficult task due to its nonlinear characteristics including flow/pressure relation, etc, the paper proposed a data-driven control method based on the model-free adaptive control. The simulation results show that the model-free adaptive control method satisfies the performance of servo control system, and provides the electro-hydraulic servo control system with new ideas and new methods.
