Abstrakt:

Structural damage detection and vibration control have been actively studied in the past decades. However, in most previous investigations, these two aspects have been treated separately according to their individual primary objectives pursued. Although structural identification and model updating have been used in the adaptive control techniques, it is still necessary but challenging to study the on-line integration of structural damage detection and optimal vibration control. In this paper, a technique is proposed for such purpose. First, on-line structural parameter identification and on-line detection of the onset, locations and extents of structural damage of controlled structures with partial measurements of structural acceleration responses is studied. An algorithm is proposed based on the extended Kalman estimator/Kalman estimator and error tracking. Then, the updated structural models are on-line integrated with the instantaneous optimal control scheme to reach the goal of optimal active structural control of the undamaged/damaged structures. Numerical simulation results with different structural damage patterns illustrate the performances of the proposed technique for the on-line integration of structural damage detection and active optimal vibration control.
