Abstract: By the large scale structure continuous synchronous lifting technology，the supporting structure with four jack-up points and each  point with four jack-up hydraulic cylinders was used for the system.The  volume synchronization control mode was applied in the single jack-up  point based on synchronous split-flow hydraulic pump.The multi-point  master-slave control mode was used between the jack-up points based on  displacement fuzzy control.The system based on synchronous split-flow  hydraulic pump and displacement fuzzy control was modeled and  simulated.The system prototype tests and the data analysis were 
completed.The results show that due to the various factors in the actual  conditions，the actual errors are bigger than the simulated one but still  meet the requirements of synchronization.The results validate the  application feasibility of the hydraulic control systems.
