Description

This study considers active vibration control of a multi-story structure which consists of bar-connected masses repeated in the vertical direction with active mass drivers installed on the top. As an alternative to the vibration mode approach, the traveling wave approach is applied. To implement the impedance matching controller which is proposed for a damped mass-spring system, the loop shaping design procedure is used to consider the dynamics of the actuator and the sensor noise. The designed controller has similar properties of the impedance matching controller, that is, it is efficient for the disturbance at any position and the towers with any stories. Experimental results are shown to evaluate efficiency.
