This project is part of a research field focused on developing active hydrodynamic bearings with magnetic tilting-pads aiming at controlling lateral vibration of rotating systems. In this project, a self identification system will be developed to be implemented in the active bearing in study. The actuators will be used, momentarily, as exciters in the dynamic identification of the rotating system in operation. After obtaining the dynamic response of the system, the stable gains of a linear controller are determined following predefined performance specifications, and the feedback loop of the system is finally closed. By the end of this project, one will have an actuation system for controlling lateral vibration in rotating systems able to identify system characteristics and to determine the necessary stabilizing gains of the controller.
