Abstract

The purpose of the provided work - the systematized analysis of the model oriented fault detection procedure. The main concept of the model-oriented methods of identification, localizations and identifications of faults are applications of mathematical model of a subject to control, as analytical or program redundancy, instead of hardware reservation. Advantage of such method is that the behavior of a system can be predicted in real time. It is defined that the considered method of fault detection is more effective, than the alarm oriented methods as in this case the bigger number of the prior information on a system is used. It is noticed that deduce of high-quality mathematical model of a controlled object demands application of well checked methods of modeling of systems that is connected with difficulties of both analytical, and computing character. The generalized concept of the model oriented procedures of fault detection is considered. In details considered features of diagnostics of faults in real time. The relevance and expediency of carrying out further researches in this direction is defined.
