Based on the purpose of suppressing the whipping effect of top building of lift ship structure, roof MR intelligent isolation system is presented in this paper. After establishing the mechanical model of intelligent isolation structure system, fuzzy control design methods of seismic response for top building of lift ship structure are developed. By taking a real lift ship structure to be built in China as a background, fuzzy control systems of roof MR intelligent isolation system for reducing seismic response of top building of lift ship structure are designed. Simulation analysis of control strategies and studies of parameters of MR damper demonstrates that the installation of appropriate roof MR intelligent isolation system and fuzzy control strategy are beneficial to suppressing effectively the seismic whipping effect of top building of lift ship structure with uncertain stiffness, and the fuzzy controller is capable of keeping superior stability.
