Метод иерархического макромоделирования в задачах анализа линейных электрических эквивалентных схем в САПР
In this paper we propose a method of modeling linear equivalent electrical circuit formed by artificial elektroanalogy based on their two-stage reduction. In the first step of the simulation model of each sub-circuit of the initial scheme formally converted into a macro model that reflects only its expressions like "input-output". In the second stage model consisting of macro models, is converted to the next hierarchical level of the macro model. The mathematical apparatus of macro-modeling is based on the inversion in the analytical form of polynomial regular high degree matrices. The proposed method can significantly reduce the complexity of modeling and multivariate analysis of large equivalent electrical circuits.
