In this study, the active vibration control system design of a composite beam with three different lamination angles under forced vibration was investigated. The produced composite beam lamination angles have been selected as {0°, 90°, 0°, 90°}s, {− 30°, 60°, − 30°, 60°}s and {− 45°, 45°, − 45°, 45°}s for investigating the vibration characteristic. Different types of bluff-body geometries were attached to the free end of the cantilever composite beams. In this way, the composite beam's vibration amplitudes have more fluctuated with the help of bluff body geometries. Bluff body structures are generally preferred in energy harvesting applications by increasing the vibration in beams. The fact that this structure, which increases the vibration amplitude, is handled in an active vibration control mechanism adds a different novelty to the subject. Flow-induced vibrations were obtained for a particular period by applying air load on it. Two different geometries of bluff bodies were placed in a freestream airflow at a constant speed to trigger and enhance the vibration of the composite beam. The front surface areas of two different bluff bodies exposed to air load are identical. Therefore, the difference in the vibrations characteristics was only affected by the geometrical differences in the lateral areas of the bluff bodies. To demonstrate this situation, the airfoil efficiency was investigated for the bluff body geometries. A piezoelectric patch is attached to the surface of the composite beam, and the vibration control is acquired utilizing the PID control design. As a result of experimental studies, it has been shown that the forced vibrations on the composite structure can be suppressed successfully with the application of the PID control design.
