In this paper, a hydraulic servo system with rod pump dynamic testing device is taken as an example to introduce the design process of hydraulic system and computer control system of large-scale high-speed electro-hydraulic servo system. Proposed a hydraulic servo system suitable for large-scale hydraulic cylinders and load parallel arrangement program, effectively reducing the size of the system. The application of iterative self-learning control strategy in large-scale high-speed electro-hydraulic servo system is studied. The actual control results are given. It is verified that the iterative self-learning control algorithm can effectively improve the control precision and dynamic response of large-scale high speed electro-hydraulic servo system.
