The invention provides a control flow and a synchronous compensation method of a test system composed of multiple oil-gas supports, and the basic work flow of the method comprises additional gas chamber pre-pressurization, oil cavity pressure closed-loop control and piston displacement closed-loop control. By adopting a synchronous compensation method, the displacement synchronism and the bearing consistency of a plurality of oil-gas supporting pistons can be kept, so that the stable lifting of a test piece and the safety of the test piece are ensured. 本申请提供了一种多台油气支承所组成的试验系统的控制流程和同步补偿方法，该方法的基本工作流程分附加气室预充压、油腔压力闭环控制、活塞位移闭环控制，在试件上浮、下落及中位位置保持过程中，采用同步补偿方法可保持多台油气支承活塞位移的同步性及承载的一致性，从而保证试验件的平稳托举及试验件的安全。
