Methods of Increasing the Reliability of Solving the Problem of Diagnostics of Electrical Circuits

Methods for increasing the reliability of solving the problem of electrical circuits diagnostics. In the presence of inaccurate measurements and uncertainty of a priori information, the diagnostic model should be considered as a set of inconsistent linear equations and to seek the solution based on, for example, the method of least squares (MLS). The solution obtained satisfies the minimum of the sum of the squares of the residuals, but does not ensure the fulfillment of a number of other requirements entering into the initial system of the problem of electrical circuits diagnostics. And this requires adjusting the solution within the MLS. The present work is devoted to the adjustment issues. The algorithm based on the use of a correction factor in one component equation is proposed both for obtaining a solution that satisfies the active constraints, and for the exact implementation of the component relation.
