Abstract
A method for identification of equivalent mathematical model with minimum order by the critical frequency for multi-dimensional dynamic object that allows linearization is suggested in the paper. It is confirmed that the minimum order of equivalent model is three and that algorithm of the method of identification of its model based on the joint solution of the system of four nonlinear equations, two of which are synthesized from the boundary conditions for the minimum and the critical frequency of the dynamic object range, and the other two are synthesized by application of the least squares method to the optimization criteria related to the logarithmic amplitude frequency characteristics of the object.
