Beznosyk O. Automatization of synthesis of circuit macromodels of components described by systems of differential equations

The dissertation is devoted to the investigation and development of the methods of automatization of synthesis of circuit macromodels of components described by the systems of differential equations. The features of construction of the circuit equivalents for systems of Cauchy's ordinary differential equations are investigated, and the possibility to create an automatized system to construct respective macromodels is shown. The method to construct the circuit macromodels of the components described by the systems of differential equations in partial derivatives based on the usage of the electromechanical analogies principle is improved. The methods of the reduction of macromodels presented as circuit equivalents, which take into account the features of a field of their usage, are developed. The possibility to use the optimization methods specific for circuit level CAD systems to adjust parameters of the macromodels obtained is approved. The technique of the automatized synthesis of the circuit macromodels of the components described by the systems of differential equations in partial derivatives that includes the stages of construction, reduction and parameters' optimization of a macromodel is developed. The methods developed are implemented as a software compatible with NetALLTED application package and tested at the NTUU "KPI" cluster.
