The present study incorporates the use of active feedback control mechanisms to suppress unwanted vibration. The basic active damping scheme involves the introduction of a control force on the structure from a feedback network whose input is dictated by the motion of the structure. The control force is applied to the rotor bearing support housing via a piezoelectric actuator attached to the rotor casing. The current research extends previous electromechanical simulations by incorporating a flexible finite element shell model of the casing to support the actuator an sensors. Actuator and feedback loop dynamics are included in the stability and response simulation.
