Abstract：In order to suppress internal force coupling of a parallel driven electro-hydraulic system, a dynamic model of the vibration system was established and the causes of coupling disturbance were analyzed.Then, the degree-of-freedom decomposition was applied to realize independent control of eight exciters, an internal force decoupling controller was applied to eliminate the coupling internal force in the process of operation.On this basis, a three-variable controller was applied to realize acceleration closed-loop control of the electro-hydraulic system and improve dynamic characteristics of the vibration system, and a feedforward inverse controller was applied to expand the system bandwidth.Performances of the proposed control strategy were validated through experiments using a parallel driven electro-hydraulic testing rig, and the experimental results demonstrate that the proposed control strategy can improve vibration accuracy.
