Abstract

Background. The objects of the study are diagnostic systems of electrical circuits. The research subject is mathematical models of circuits and processes of their diagnostics. The aim of the study is to form a general statement of the problem of diagnostics of electric circuits and approaches to its solution based on the results of modeling the object of diagnosis and the process of diagnosis.
Materials and methods. Methods of analysis, synthesis and identification of electric circuits, apparatus of linear algebra, including matrix calculus, methods of verification and validation of mathematical models were used for mathematical description of diagnostic objects and diagnostic processes.
Results. The statement of the problem of diagnostics of an electric circuit is given and the general approach to its decision which consists in construction of algorithmic models of diagnostics on the basis of the results of multilevel modeling of the object of diagnostics is formulated.
Conclusions. The proposed approach can serve as a methodological basis for improving the known and searching for new methods and diagnostic tools.
