Fault diagnosis for actuators of an intensified multifunctional heat-exchanger from the view of both plant and component levels

Autor: Qin Mu Wu, Mei Zhang, Boutaieb Dahhou, Ze tao Li

Publikováno v: International Journal of Modelling, Identification and Control. 36:1

This paper proposes a fault detection and diagnosis (FDD) approach to the nonlinear model of the intensified heat exchanger system locally and globally. It implements the optimal performances monitoring on both internal dynamics of each component and

Actuator fault diagnose for interconnected system via invertibility

Autor: Ze tao Li, Michel Cabassud, Boutaieb Dahhou, Qin Mu Wu, Mei Zhang

Publikováno v: International Journal of Modelling, Identification and Control. 33:283

This paper deals with the problem of actuator fault diagnosis for a class of interconnected invertible nonlinear systems. For that, the actuator is viewed as an independent dynamic subsystem in series with the plant dynamic subsystem, thus forming an
