Abstract	In order to solve the difficult problem that traditional fuzzy logic control (FLC) strategy shows dissatisfactory control effect when facing different control objectives and load actions, this paper proposes a variable universe-based self-adaptive fuzzy control strategy (VAFC) theory. This strategy improves the performance of the FLC strategy by adjusting the universe of FLC input and output variables online, and designs the self-adaptive law of output universe based on Lyapunov function. This paper introduces modified clipped-optimal (MCO) into VAFC active control strategy and puts forward VAFC/MCO semi-active control strategy. In this paper, seismic responses of three-span continuous girder bridge under the control of VAFC/MCO, FLC/MCO and LQG/MCO are analyzed respectively, and the results show that the VAFC/MCO strategy has more significant seismic reduction effects than the FLC/MCO and LQG/MCO strategies do.
