Active monitoring and vibration control of smart structure aircraft based on FBG sensors and PZT actuators
چکیده انگلیسی
Active vibration monitoring and control system becomes a very hot topic in recent years with the rapid development of smart materials, sensing technology and actuating technology. A smart aircraft model is constructed using fiber Bragg grating (FBG) sensors and piezoelectric ceramics. Vibration shape reconstruction of the aircraft model is achieved using discrete fiber Bragg grating sensors based reconstruction method. Vibration control is achieved by employing modified multi input multi output (MIMO) hybrid filtered-x least mean square (FXLMS) control algorithm with online identification and reference signal self-extraction using distributed piezoelectric patches. An experimental platform was constructed, and experimental verifications were done. The results show that the proposed reconstruction method is effective for real-time shape reconstruction of the aircraft model, and the structural vibration response is suppressed to a great extent by the proposed vibration control method.
