Study on Moving Pattern Based Fault Detection Method

Abstract

In our previous work, moving pattern based modeling and control was proposed. In this paper, based on our previous work, a fault detection method based on moving pattern is proposed, and interval number is still used to measure moving pattern. Based on the history operating condition data, moving pattern based dynamic model is formed. The model gives the pattern class to which operating condition patterns belong, and whether the fault is happened. In addition, the nearest neighbor pattern and secondary nearest neighbor pattern are defined in this paper. At last, the validity of the proposed fault detection method is verified by the practical operating condition pattern data of the sintering process of Anyang Steel and Iron Works.
