This paper presents the development of a bilinear system model and the application of a bilinear fault detection observer to a papermaking machine to detect various simulated faults. First a suitable MIMO bilinear model representation of the wet end section of the process is found. Then, a set of robust bilinear fault detection observer is used to generate the residuals which are robust to disturbance...
Feedforward and feedback control is developed in this work for proton exchange membrane (PEM) fuel cell (FC) systems to do fault detection and isolation (FDI). The fault detection is achieved using a radial basis function (RBF) network model, whilst the fault isolation is based on the RBF classification. One actuator fault, one component fault and three sensor faults have been introduced to the PEMFC...
Locating high-resistance grounding faults poses a tough and challenging problem for the safety of DC railway systems. High-resistance grounding fault current isn't sufficient to trigger switches, which may expand the accident or turn into potential hazards. In order to overcome the limits of the existing methods (such as signal injecting method, resistance method and so), developing a novel fault...
This paper presents a simulation model of DC traction system which is based on bilateral power supply mode. The model of two substation rectifiers in one track section has been proposed which is according to practical situation. The modeling was conducted with respect to the variations of the starting-up process and short circuit conditions. By comparing and investigating the simulation results of...
