Abstract
Chaotic vibration is a very interesting phenomenon to our machinery dynamics researchers, and it may occur in many mechanical systems. An example is Duffing system in which many kinds of vibrations exist. In this paper, we deal with the chaotic vibration of a Duffing model, and apply OGY method to control the chaotic vibration. From the results we confirm the validity of our developed numerical method of calculating approximate discrete system around the neighborhood of a target unstable state from the continuous system for applying the OGY method.
