Applications of a magnetorheological damper to vibration suppression of a three-story building

This paper presents a magnetorheological damper applied to suppress vibration of a three-story building. The damping force is obtained through the Buc-Wen model, and then an inverse damper model is built up by the adaptive neuro-fuzzy inference system (ANFIS). To facilitate the vibration suppression, a semi-active control is designed, where a PID control is used to evaluate the desired damping force based on the building vibration and then the ANFIS model is used to calculate the desired damper current. The current is applied to the damper so as to generate a damping force to suppress the vibrations. The proposed approach is demonstrated through numerical simulations.
