The Identification problem of control object (CO) arises during design of automatic control system (ACS) or its adjustment with tools. In many respects the degree of ACS approximation depends on description accuracy of model. The decision of this problem by means of the built-in system - the industrial controller or the special module - is represented especially attractive. The Identification problem is reduced to procedure of definition of structure and parameters of mathematical models, which provide proximity of output signals of model and object according to adequacy criterion on condition that input signals of the CO and its model are identical. In this paper the Real Interpolation Method (RIM) is offered for the solution of System Identification problem. The RIM allows to create a sufficiently cost-effective algorithmic basis and to solve all complex of Identification problems. It is based on use of a special case of the Laplace transformation, when the complex variable s =δ + jω is degenerated to real δ. Due to this approach the number of operations is diminished more than 2 times in comparison with the frequency method.
