This paper presents a novel technique for Active Vibration Control (AVC) based on updated mathematical model of a mechanical structure. Vibrations of a smart plate instrumented with PZT sensor and actuator are suppressed using a negative velocity feedback controller. The AVC controllers are designed and compared for two cases. In first case it is assumed that there is a mismatch between the analytical model and the actual structure. In the second case the mismatch in analytical model and actual structure is compensated using direct method of model updating. Numerical simulations carried out in MATLAB software for these two cases demonstrate the improvement in performance of the AVC controller when updation is carried out. [ABSTRACT FROM AUTHOR]
