Abstract:

The possibility of enhancing Tuned Mass Damper (TMP) effectiveness with an added active control capability is presented in this paper. The weighting matrix associated with the components of the state vector are discussed. The relationship between response variance and elements of weighting matrix are examined from which the arrangement of the weighting matrix associated with the components of the state vector are determined. A predictive control law has been developed in which emphasis is placed on compensation for the time delay due to the control action. Numerical examples are worked out to demonstrate the control efficiency of the proposed algorithm to the vibration of a bridge-like flexible structure.
