This paper deals with damage detection and vibration control of a new smart board designed by mounting the piezoelectric fibers with metal core on the surface of the CFRP composite. The damage of the board is identified on the assumption that the piezoelectric fibers using a sensor and actuators are broken at the damaged location simultaneously. A finite element model a CFRP cantilever is established and the damage location is identified using the input-output signals. Furthermore, the liner fractional transformation (LFT) is formulated considering the damage location and the gain-scheduled controller considering the location is designed. The control performance of the proposed method is verified by simulation.
