Vibration control of Multi Degree of Freedom structure under earthquake excitation with TMD control and active control force using fuzzy logic method at the highest and the lowest story of the building

Abstract

In this paper, Control system performance, as a passive and active control on the example building under the Bam earthquake excitation, was studied. In order to passive and active control the structure TMD system mounted on the top floor of the building and FLC method was used, respectively. Active control system first applied to the lowest floor then to the highest point of the structure (applied to the TMD system). Mathematical model of the building is established in MATLAB. Equation of motion was written for high rise building and it was solved by state-space method, the Results are illustrated and compared.
