Nonlinear dynamical systems, which are common in modern technological and natural processes, despite the determinism of their determination, can exhibit chaotic properties in their dynamics. At the same time, arbitrarily small perturbations in the input influences and parameters of the system itself result in significant but final disturbances of the output signal. This leads to some difficulties in designing, managing, and forecasting the behavior of such systems. When mathematical and computer simulation of systems of dynamic chaos there are problems specific to these systems. First of all --- it is necessary to ensure the availability of a workable criterion of adequacy of the model. For identification purposes, the availability of such a criterion is fundamental. Most often, the criteria used in modeling the behavior of dynamic systems, based on conventional methods in the space of output signals, are disabled. As a prototype for the synthesis of new methods of identification, it is advisable to select a number of identification methods that were developed and investigated in the works of P. Eikhoff, L. A. Rastrigina, L.N. Fitzner, E.E. Gachinsky, AI Drozdova, OI Mikhalova, in particular search and adaptive-search methods. It is also considered appropriate to use as a basis for the next class of two-model adaptive-search methods that were developed and investigated in previous work. However, the results of the simulation of these methods by the methods of identifying these methods of technical objects that exhibit complex and chaotic dynamics, have shown their complete or limited inapplicability.
