    Abstract

    Presented in this paper is the development of a control law for tuning a variable stiffness vibration absorber to attenuate single frequency excitation in a non-collocated situation. The control law is comprised of two distinct parts. First, a feedback controller is used to obtain a ±90° phase condition between the motion of the vibration absorber mass and the location of interest. Next, a feedback based tuning strategy is used to precisely tune the vibration absorber for performance maximization. The feedback based tuning is based on the classical feedback structure of a regulating system and is used to tune the absorber such that the accelerometer voltage resulting from the measurement of vibration of the point of interest is minimized. An experimental verification of this control law is shown.
