Abstract
Сertain problems of test diagnosing of electric circuit on the basis of application of a matrix which elements are linearly related with the desired internal parameters are considered. Use of redundant experiments is presented. Analytical solutions of a task when the part of required parameters is known and way of diagnosis of multipole network with inaccessible nodes are received. Examples are showed.
Highlights
Based on achievements of the classical circuit theory, one of the most natural initial approaches to the diagnostics of electric chains is representation of diagnosed circuit in the form of a passive multipole network. Parameters of this multipole network are subject to definition
The criterion for the solution of the diagnosis is to determine the numerical values of the internal parameters of the elements diagnosed circuit
That if there are no parallel branches in the circuit, the structure and the numerical value of the immitances of all the branches may be easy restore based on the matrix Yn
Summary
Based on achievements of the classical circuit theory, one of the most natural initial approaches to the diagnostics of electric chains is representation of diagnosed circuit in the form of a passive multipole network. Parameters of this multipole network are subject to definition. The criterion for the solution of the diagnosis is to determine the numerical values of the internal parameters of the elements diagnosed circuit (resistors, capacitors, etc.). One of the most difficulties of the solution problem lies in the fact that the analytic relationship between the measurements and the required elements parameters are non-linear even for linear resistive circuits.
