Active vibration control of large flexible structures
Abstract
Active vibration control of large and complex structures is described. An important problem of actively controlling large flexible structures is one of compensating for control and observation spillover when a large dimensional system must be controlled by a much smaller dimensional controller. A modal control design procedure is developed which not only insures that the controlled structural modes stay close to the designed values but also preserves stability in the uncontrolled modes. The sensitivity of spillover compensation to the placement of controllers and sensors is also studied.
