Abstract

Adaptive-passive vibration control achieves robust attenuation of a harmonic excitation through tuning a reactive device. In this paper, a robust tuning strategy is presented for adaptive passive control. The tuning strategy is based on minimizing the voltage amplitude from an accelerometer. This is similar to the standard regulator problem in feedback control. However, the feedback signal is an even function and therefore tuning direction is ambiguous. One tuning direction scheme is developed which compares the natural frequency of the absorber to the excitation frequency. Experimental verification of the tuning strategy is presented.
