Abstract: This study considers the issues of mathematical modeling in case of multi-parameter control. The purpose of the article is to substantiate the necessity of taking into account the design features of the sensor when constructing mathematical models for multi-parameter control, and to develop a methodology for determining the generalizing characteristics — the design sensitivity coefficient of an eddy-current converter. The methodology is based on the analysis of hodographs of the eddy-current control. Simulation experiments in order to calculate design sensitivity for each control points as well as for every thickness of samples and for each size of gaps have been carried out. The obtained results allow us estimate design efficiency of the used eddy-current sensor.

Keywords: eddy-current test, design feature of the sensor, design sensitivity of eddy-current converter.
