In vibration control of smart structures, piezoelectric sensors/actuators are usually bonded to the surface of a host structure. Debonding may occur between the piezoelectric sensors/actuators and the host structure, and it may decrease the control efficiency of vibration suppression or even lead to an unstable closed loop control system. This paper investigates the effect of the debonding on vibration control of beams with piezoelectric sensors and actuators. Presented is a novel model, which takes into account both flexural and longitudinal displacements of the host beam and piezoelectric layers as well as the peel and shear strains of the adhesive layer. Both collocated and non-collocated control schemes are used to study the effects of sensor or actuator debonding on active vibration control of smart beams.
