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 noncollocated situation. The control law is comprised of two distinct parts. First, a ±90° phase condition between the motion of the vibration absorber and the location of interest is used to determine tuning direction. Next, a feedback based tuning strategy is used to precisely tune the vibration absorber for performance maximization. The feedback tuning strategy is based on the classical feedback structure of a regulating system. The absorber is tuned 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.
