Application of Sensor Fault Diagnosis Based on Information Fusion Techniques

In order to improve the reliability of fault detection and diagnosis(FDD) for material test machine,it is important to make full use of the information from being test material knowledge and material measurements.An application of information fusion in FDD is presented.In the proposed method,the fusion adopts multiple FDD strategies aiming at angle sensor and torque sensor etc of the system,then the results of these strategies are fused.Through regression analysis on the fused data,the information fusion techniques are showed to be practical and effective.
