Vibration Control of a Marine Structure with Magnetorheological (MR) fluid Dampers

Marine structures are exposed to different excitations have been substituted by the MR dampers. Prevention of serious damage to marine structures, particularly due to vibrations might be achieved by monitoring the loading conditions and by inspecting the structural integrity. Controlling vibration of a marine structure in order to prevent the collapse of these structures is main goal of this research with utilizing Magnetorheological (MR) fluid dampers. The controlling method is employed by an optimal control strategy, the linear quadratic regulator (LQR) as controller of this system. The preliminary results show that to reduce the amplitude of these vibrations.
