A Novel Approach to Detect Little Offset Fault of Sensor for Linear Dynamic System
In this paper, a novel approach to measure little offset faults of sensor for Linear Dynamic System is proposed. The method uses Kalman filter to acquire the residuals of the sensor and uses Sequentical Probability Ratio Test to detect the fault based on multi-residuals, which can get the least number of the residuals by dynamical calculation and has some adaptive characteristic. A simulation is given to illustrate the proposed method, and the simulation also shows that the method can resolve the problems of real time, and promote the detection accuracy which detects a fault using the residuals.
