A practical demonstration of a large-scale active vibration system has been described in this article. Decentralized feedforward control was applied using four hydraulic actuators which were attached between a floating raft and a flexible hull-like structure. There were also eighteen rubber isolators in parallel with the actuators. Up to 36 dB reduction in the vibration of the hull-like structure was achieved at some tonal excitation frequencies, while the passive isolators were effective at controlling broadband vibration transmission, especially at high frequencies.
