Comparison of semi-active dampers in seismic isolation

Journal Article

Since the energy cost of active vibration control is an important problem and the performance of the passive devices is limited, semi-active control devices have received much attention in recent years. In this paper, we compare the performance of two pseudo-skyhook control methods; a bang-bang control and a continuous control to passive viscous control and the optimal semi-active control. Numerical results show that the proposed control rules perform almost as well as the optimal semi-active control and can overcome the deficiency of the passive viscous control at high frequency range. © 2004 ASCE.
