Abstract:

In a first step the vibration modes of the plate were identified by using a laser vibrometer. Then the actuators (piezo elements) and sensors (accelerometers) were placed on the plate in such a way that all the modes are controllable and observable. It was then possible to identify the dynamics of the whole system (including the amplifiers, filters etc.) with the established algorithms for lumped parameter systems. Then a controller was designed and implemented with the aim of minimizing the vibrations of the plate. Finally the results of the uncontrolled and controlled system were compared and some conclusions regarding influences from disturbances were drawn.
