Abstract: In this paper, a new synchronization loop structure of hydraulic system was built. The mathematical model and mechanical structure of the key element A11VO proportional variable pump in the hydraulic system were established based on transfer function. And the open-loop transfer function model was completed. Besides, the design of the control strategy was completed and the dynamic characteristics of system was improved. It can provide reference for the follow-up research of hydraulic gate hoist.

Keywords: hydraulic system; proportional variable pump; dynamic characteristics
