For hydraulic synchronous jacking operations involving large-scale structures with weights exceeding 1,000 tons and large volumes, particularly when multiple modular units are coordinated for jacking, the poor asynchronous operations can easily lead to uneven force distribution, and then result in the object to tilt or overturn. So, it is important to research the hydraulic synchronous control technology. Based on analyzing the working principles of hydraulic jacking systems, a joint simulation model integrating hydraulic and control systems was constructed in AMESim and Simulink. For the problems such as slow response, large synchronization errors, and nonlinearity during system operation, the effectiveness of three hydraulic synchronization control strategies, including cross-coupled control, master-slave control, and parallel control, are analyzed. Taking a 400t*4-cylinder system as an example for co-simulation, the results shows that the cross-coupled control strategy outperforms the other two in terms of maximum dynamic error and time to reach stability, which can better meet the control requirements for smooth and rapid operation of the jacking system.
