TIME DOMAIN PARAMETER IDENTIFICATION OF ANTICORROSION COATING VIA SOME TYPES OF POLYNOMIAL SIGNALS

Marek Niedostatkiewicz, Romuald Zielonko

Abstract

The paper presents a time domain method of anticorrosion coating diagnosis on the level of equivalent circuit parameter identification, based on applying a set of shape-designed polynomials and measuring the object’s responses (so-called observables) at a given time T. Equivalent circuit parameters are calculated directly from observables using analytical equations, determined by modelling circuit topology. In the paper the comparison of different polynomial signals (Chebyshev, Legendre, Optimal) against the criteria of stationary error propagation is presented, on the base of analytical and simulation results.
