Nonlinear Multimode Industrial Process Fault Detection Using Modified Kernel Principal Component Analysis

open access: yesIEEE Access, 2017
Kernel principal component analysis (KPCA) has been a state-of-the-art nonlinear process monitoring method. However, KPCA assumes the single operation mode while the real industrial processes often run under multiple operation conditions.

Fault diagnosis method of train control RBC system based on KPCA-SOM network

open access: yesJournal of Measurement Science and Instrumentation, 2020
Radio block center(RBC) system is the core equipment of China train control system-3(CTCS-3). Now, the fault analysis of RBC system mainly depends on manual work, and the diagnostic results are inaccurate and inefficient. Therefore, the intelligent fault
