The attenuation of structure vibration is very slow when flexible strucure is stirred external force. It seriously affected the life of flexible structure. Smart structures used piezoelectric ceramics as actuators are an effective manner to solve the problem. This paper uses Fiber Bragg Grating (FBG) as sensors and piezoelectric ceramics as actuators to study the active vibration control for the resonance of the smart beam. Two groups of piezoelectric ceramics will be used for vibration exciter and vibration abatement, respectively. The fiber smart beam is excited to a sharp vibration nearby the particular resonance frequency by controlling the frequency of the vibration excitation. The vibration signal is measured by the FBG sensors and the close loop feedback control is fulfilled by the vibration abatement group, and the vibration amplitude of the fiber smart beam is abated. The experiment results show that the resonance amplitude of the beam is obviously abated by adjusting the frequency, amplitude and phase of the vibration abatement circuit.

This article describes a design method to size smart structures with piezoelectric ceramics. The method makes it possible to determine the amplitudes of vibrations that may be generated by piezoelectric ceramics bonded on a metallic or composite structure. One of the possible applications of the method is the preliminary design of smart structures for active vibration control. This case is particularly treated in this article. The method is based on a reduced model that can be established using a multiphysics FEM software. This model can also be used to compute the control law for vibrations attenuation.
