This paper features the modeling and design of a PID controller to control the vibrations of a smart thin walled composite box beam. Collocated piezoelectric patches are bonded as sensor / actuator to the master structure at a certain finite element location on the beam, i.e., nearby the fixed end of the composite box beam. The beam structure is modeled in the state space form using the concept of piezoelectric theory, the Timoshenko beam theory and the Finite Element Method. The beam is subjected to an external disturbance (say, impulse or sine or random excitation). A novel PID controller is designed for the smart composite box beam. When the designed controller is put in the loop with the plant, i.e., the smart structure plant, the plant performs well and the vibrations are damped out in a quicker time. The performance of the designed controller is thus evaluated for vibration control and the conclusions are here by drawn. The simulation results show the effectiveness of the developed method. This is the main objective of this paper.
