Abstract
This paper describes the active vibration control of a plate using a self-sensing actuator (SSA). In self-sensing actuator, the same piezoelectric element functions as both a sensor and an actuator, so that the total number of piezoelectric elements can be reduced. Many studies have been reported on the application of self-sensing actuators to the vibration control of beams. In this study, the application of self-sensing actuator was extended to the active vibration control of a plate. The adaptive filtered-X LMS algorithm is adopted in the control. The effectiveness of the control method was confirmed in the experiment, and the results show that the vibration level is considerably reduced at many peaks.
