This paper presents modeling and vibration control design of thin lightweight plates taking into account defects. The classical plate theory in bending is used for a finite element dynamical model. Defects are modeled in a smeared-type way by changing the physical parameters of the corresponding element. Optimal control is further studied for plates with defects supplied with sensors and actuators. LQR and H2 control schemes are considered for vibration suppression. The influence of the plate's defects on the control of the vibrations is investigated. The placement of control forces and their influence on the quality of the vibration-regulating process is considered. Numerical simulations are carried out in order to demonstrate the efficiency of the proposed control strategies.
