Active vibration control of a multi-degree-of-freedom structure by the use of robust decentralized simple adaptive control

In this paper, we discuss the problem of active vibration control of a multi-degree-of-freedom structure, such as a high-rise building, using robust decentralized simple adaptive control (RDSAC). Such multi-degree-of-freedom structures have inherent dynamics that can be adequately represented by mass-spring-damper subsystems. As a result, it is shown that we can achieve good vibration absorbing performance concerning the reduction of the effect of disturbances and interactions by applying the RDSAC to only a few "target" subsystems of the plant. Stability of all signals in the vibration control system is guaranteed and the effectiveness of the proposed methods is confirmed by experiments.
