Chunhui Zhao, Auteur ; Youxian Sun, Auteur ; Furong Gao, Auteur |Time-varying fault characteristics have not yet been addressed by conventional fault-reconstruction-based modeling methods, which could affect fault diagnosis performance. In the present work, the multiple-time-region (MTR) nature, that is, the [...]

Chunhui Zhao, Auteur ; Furong Gao, Auteur ; Youxian Sun, Auteur |In the present work, a monitoring strategy based on between-set regression analysis is developed for the online monitoring of processes with multiple "modes". The definition of modes here differs from the conventional ones in that, the modes her[...]
