This importance is much apparent when it is about\na complex system such as the nuclear reactor with pressurized water\nof several form with various several non-linearity and time scales. In\nthis case the analytical approach is heavy and does not give a fast\nidea on the evolution of the system. The tool Bond Graph enabled us\nto transform the analytical model into graphic model and the\nsoftware of simulation SYMBOLS 2000 specific to the Bond Graphs\nmade it possible to validate and have the results given by the\ntechnical specifications. We introduce the analysis of the problem\ninvolved in the faults localization and identification in the complex\nindustrial processes. We propose a method of fault detection applied\nto the diagnosis and to determine the gravity of a detected fault. We\nshow the possibilities of application of the new diagnosis approaches\nto the complex system control. The industrial systems became\nincreasingly complex with the faults diagnosis procedures in the\nphysical systems prove to become very complex as soon as the\nsystems considered are not elementary any more. Indeed, in front of\nthis complexity, we chose to make recourse to Fault Detection and\nIsolation method (FDI) by the analysis of the problem of its control\nand to conceive a reliable system of diagnosis making it possible to\napprehend the complex dynamic systems spatially distributed applied\nto the standard pressurized water nuclear reactor.","references":"[1] J DE Ladonchamps et J.J Verdeau \u00ab R\u00e9acteurs nucl\u00e9aires a eau\npressuris\u00e9e : th\u00e9orie, technologie et applications a la propulsion\nnavale\u00bb, Masson e Cie \u00e9diteurs, 1972\n[2] A.
