Knowledge Acquisition for Fault Diagnosis Based on Rough Theory
Haifeng He · Control Engineering of China · 2011
It is the topic of the day to diagnose fault and manage health using flight data.The relationships between the flight data and the fault mode are needed when to diagnose fault using flight data,but the knowledge can not be obtained from maintenance handbook.The logistic relationships between the flight data and the fault mode are connotated in the abundant historical flight data.Therefore the knowledge acquisition method based on rough set theory is proposed in the paper,and the algorithm is realized.Simultaneity the validity of the method is proved by the actual data.
