The Fuzzy Logic Semiactive Control Of Structure Adding Magneto-rheological Damper

Firstly the paper has carried on the analysis about kinds of control strategy and the control implement in the field of structure vibration control. Then the model of numerical simulation of structure vibration control considering the liner and nonlinear as a substitution of the conventional dynamic response time interval analysis method, is constructed by a simulation tool in Matlab called simulink. And the validity of this model has been confirmed; In order to precisely control the structure adding the magneto-rheological damper and be able to make the control decision instantly, the fuzzy logical entire condition control was introduced and determines the controller deciding the input electric current of MR damper. According to the status equation of the structure controlling system and dynamic response simulation analysis model established in this article, I designed and established semi-active control simulation model using the MR damper under the Simulink environment. Finally this paper calculated the example structure input bidirectional earthquake wave and carries on the simulation, proved the validity of the model and the control method.
