Seismic Design of Magneto-rheological Dampers between Different Sizes Buildings under Optimum Parameters
Abstract
The effectiveness of optimal semi-active
dampers for reaching the optimum gains of the response of the adjacent
buildings connected by magnetorheological (MR) dampers subjected to seismic
motion is examined in this study. One of the challenges is to improve an
effective optimal control strategy, utilizing the capabilities of the MR
dampers. Hence, a SIMULINK block in MATLAB program was developed to compute the
desired control forces at each floor level and to the obtain number of dampers.
Linear quadratic regulator (LQR) and linear quadratic Gaussian (LQG)
controllers are used for achieving the desired control forces, whilst the
desired voltage is synthesized based on clipped voltage law (CVL). The control
objective is to diminish both the displacement and acceleration responses. As a
result, MR dampers can deliver noteworthy displacement response control that is
possible with less voltage for the shorter building.
