Abstract :
This paper discusses structural vibration control using a semi-active magnetorheological damper. The proposed model of MR damper expresses the hysteresis effect compactly, and can be used to obtain an inverse dynamic model so that the desirable damper force by LQG control should be added to the structure in an online adaptive manner. Finally, the total adaptive algorithm can work effectively.
