Abstract
For vibration control applications, a collocated input/output response is generally desired. A perfect sensor/actuator collocation usually provides a stable performance in closed-loop feedback controls. Self-sensing actuators of various types have been proposed, but they still show several problems such as hysteresis, phase error, non-linear response, and complexity of the compensation technique. This paper presents a new patch-type self-sensing actuator based on an extrinsic Fabry-Perot interferometer and a piezoelectric ceramic. The proposed self-sensing actuator not only guarantees stabilities in 'direct-feedback control loops' such as in existing sensoriactuators but also has better strain resolution and a wider dynamic sensing range. Finally, the application of active vibration control is demonstrated using the self-sensing actuator developed.
