Application of semi-active control strategies for seismic protection of buildings with MR dampers

Hybrid geno-fuzzy controller for seismic vibration control

“…Genetic algorithms also are used for determining the rule base of a fuzzy control system for seismic vibration control with an MR semi-active damper in [8]. In comparison with an adaptive controllers, the authors have obtained a better response reduction of the structural system from the optimized fuzzy controller.…”

Parametric optimal bounded feedback control for smart parameter-controllable composite structures

“…In earlier studies, smart control devices such as magneto-rheological damper were designed and installed on structures for suppressing vibration [1][2][3][4][5][6][7][8][9]. The control forces of those devices act on structure systems as external forces so that the control systems have stateuncoupled linear control terms or external control inputs [5][6][7][8][9]. The control inputs can be designed based on the control theory such as dynamic programming principle.…”

“…Several control strategies such as linear quadratic control (or linear quadratic Gaussian control) and bang-bang control (or bounded saturated control) [20,21] have been proposed and applied frequently to the vibration control of engineering structures. In those studies, the control systems with state-uncoupled control terms were considered, where the control actions are external inputs and uncoupled with system states, for example, the control forces produced by active mass dampers and semi-active magneto-rheological dampers [5][6][7][8][9]. The feedback control law can be determined directly, for example, based on the dynamical programming principle.…”

Semi-active Control of Structure Vibrations with MR Damper Using Fuzzy Control System (FLC) and Optimization through Genetic Algorithm (GA)

“…Shook et al [10] optimized fuzzy logic controllers using Genetic algorithm and investigated the results. Finally, Bitaraf et al [11] proposed two semiactive control methods for seismic protection of structures, using MR damper.…”
