Criteria for identification of non,linear models of dynamic systems
Abstract: The paper considers the problems of structural identification of the dynamic systems on the basis of the analysis of the phase paths and their reflections in the extended phase space. The analysis of the present techniques of revealing of the non-linear structures of the dynamic model of the mechanical system has been done. On the basis of the analytical study of the phase paths properties, the method of non-linear structure revealing of the system without application of parametric estimation methods has been worked out. The method assumed by the author demonstrates the feasibility of identification of mechanical systems models with application of phase paths reflections on the plane «acceleration — displacement». The offered method is close to the method of the temporary processes treatment, but unlike of the present methods of the qualitative identification, it is not so awkward in application.
Keywords: non-linear dynamic models, phase paths reflections, phase plane «acceleration — displacement», structural identification.
