In the harsh underground environment, the transmission gear in the rocker arm of the shearer is susceptible to impact load, frequently leading to failures that result in economic losses or casualties. Therefore, real-time and accurate gear fault diagnosis is crucial. Existing diagnostic models struggle with insufficient feature extraction and low diagnostic accuracy when addressing nonlinear, nons...Show More
Effective fault diagnosis for mission-critical and safety-critical systems, such as aircraft electric power system, has been an essential and mandatory technique to reduce failure rate and prevent unscheduled shutdown. This paper aims to compare the performance of three efficient fault classifiers, BPNN, SVM and SDAE, in parametric fault diagnosis for the boost DC-DC converter in aircraft. The tra...Show More
