The present work deals with finding the optimum parameter of a control system that utilizes an electromagnetic actuator to actively attenuate the vibration amplitude of a flexible rotor-shaft-bearing system. The equations of motion of the rotor-shaft-bearing system is found out using the finite element method and the rotor-shaft is modelled by beam finite element taking into account of the effects like distributed inertia, flexural stiffness, gyroscopic effect and internal material damping. Optimum actuator location and the optimal set of actuator and control parameters are found out using Genetic Algorithm based approach, where the objective is to minimize response amplitude with least amount of control cost with a specified margin of stability. The control parameter found in this approach is quite efficient in achieving the desired objective.
