Control effects and material parameters of piezoelectric smart moment controllers



The control using piezoelectric smart moment (PSM) controllers for seismically excited structures was studied. The radical principle of PSM controller was introduced firstly and then the different formulae of control shear force for different structures were derived with the stiffness ratio of columns taken into consideration. With the active control algorithm based on the theory of modem optimal control, this study proposes a simulative computation on the frame structure and mill structure respectively, and the results indicate that the installation of this smart controller with proper parameters can significantly reduce seismic responses of different structures. The optimal parameters of the damper can be identified through a parameter study.
