Dynamic Uncertainty Analysis of Sensor Level in Mechatronic Systems For Application of Mechatronics BIT

YANG Guang, QIU Jing, LIU Guan-jun, WEN Xi-sen(Dept. of Mechatronics and Automation, National University of Defense Technology,Changsha 410073, China)  
The uncertainty of sensor level in BIT systems reflects the reliability of detection process and its output data. The reliability of data would impact upon the accuracy and reliability of the decision of BIT systems, and the uncertainty of data increases the false alarm rate of BIT systems. So the uncertainty analysis of sensor level can provide the estimation of the reliability of detection process. The general uncertainty analysis is a static process. In this article, dynamic uncertainty analysis based on the state mode space of sensor system is presented. This analysis method was based on the reliability model of sensor system. And the calculation had a probabilistic foundation. The influence of uncovered fault mode on the method was analyzed. Certain vortex displacement sensor was analyzed as the example to illustrating the method.
