Abstract
This paper addresses a smart flexible beam using a piezoelectric material with a self-maintenance for the characteristics variation. Perturbations of the piezoelectric materials capacitance of the flexible beam are caused by temperature fluctuation or breaking of wire. This paper proposed that the self-maintenance of a self-sensing system with a dynamic compensator can achieve to realize by adopting the system identification and the controller switching. Perturbation of the piezoelectric materials capacitance, experimental results by using the system identification and controller switching demonstrated the effectiveness of the proposed method.
