实验台温度控制系统灰色理论的故障诊断研究

Research on fault diagnosis about experiment platform temperature control system based on grey theory

提出了一种采用灰色系统理论来预测煤体温度数据的模型,将预测结果应用于煤自然发火实验台温度控制系统的故障诊断上,通过设定门限值可判定其工作状态是否正常.实验证明结果准确率较高.

A model based on gray system theory to predict the temperature data from coal spontaneous combustion experiment plat was put forward, and then the predicting result was applied to fault diagnosis of the temperature control system . At last threshold value was set to determine whether they are normal or not. Experimental results show a higher accuracy.
