Abstract

In the course of the vibration mitigation control of structures by using magneto-rheological (MR) dampers, the control currents of MR dampers have to be chosen accurately and quickly. The fuzzy control technology has strong robustness and intelligent characteristics, so it is used to choose the control currents of MR damper. How to design a fuzzy controller for MR damper is studied and a five-floor steel structure with five MR dampers (each floor with one damper) using the designed fuzzy controller is simulated. Simulation results of the fuzzy control structure are compared with those of the ON control structure, the OFF control structure and the uncontrolled structure. Analysis results demonstrate that the fuzzy control strategy can determine control currents of MR dampers accurately and quickly, furthermore, the fuzzy control strategy reduces seismic responses of structures more effectively than the ON control strategy and the OFF control strategy.
