Vibration Control of Plate Structures

The paper describes two approaches to the problem of active damping of vibrations of plate structures. First one is based on the full state feedback designed by the pole placement or LQ (Linear Quadratic) optimization and state observer. The incomplete pole assignment method is used instead of the standard full assignment. The second one is based on experimental identification of the first mode shape and design dynamic compensator. Both methods are confronted in regard of quality and the robustness of the control law.
