Abstract

This paper serves to highlight a potential and effective active force control (AFC) based scheme to suppress friction induced vibration that is caused by the mechanisms of negative damping and mode-coupling. Two mathematical models that are based on Shin and Hoffmann schemes are first simulated and analyzed using a conventional closed loop proportional-integral-derivative (PID) controller. Later, the models were seamlessly integrated with AFC elements to develop into a two degree-of-freedom (DOF) controller that is designed to effectively reject the disturbances and consequently reduce the vibrations in both models. It is found that the integrated PID-AFC scheme is very effective in suppressing vibration compared to the pure PID controller alone as clearly demonstrated through the results presented both in time and frequency domains.
