740 セルフセンシングアクチュエータによる平板の振動制御  [in Japanese] Vibration Control of a Plate Using Self-sensing Actuator  [in Japanese]

This paper describes the vibration control of a plate using a piezoelectric element as a self-sensing actuator. By using self-sensing actuator techniques, one piezoelectric element, which is bonded on the face of the plate, gets the information of the vibration of the plate, and produces control input simultaneously. The control input signal is generated by the adaptive control system with the filtered-X LMS algorithm. Experimental investigations are performed and the results show that the vibration level is successfully reduced at a broad frequency band.
