FUZZY-LOGIC CONTROL OF PARAMETRICALLY EXCITED IMPACTING FLEXIBLE SYSTEM

In this article, the control of a repetitive impacting elastic link wi th parametrically excited base in rotational motion is considered. A f uzzy-logic controller is designed and employed to suppress the vibrati ons resulting after the impact with an external rigid body. The moment um balance method and an empirical coefficient of restitution is used in the collision of the two bodies. The controller is applied successf ully to reduce the vibrations of the parametrically excited impacting flexible system. Simulations for several combinations of excitation an d rotation parameters are provided.
