Elements of mathematical phenomenology of self-organization nonlinear dynamical systems- fractional calculus and synergetics approach

Abstract

The modern dynamical systems of various physical natures, such as natural, social, economic, and technical ones, are complexes of various subsystems. Here, the fundamental basis of nonlinear theory of system’s synthesis based on synergetics as well as fractional calculus approach in modern control theory together with its application will be presented. Also, mathematical phenomenology of self-organization of nonlinear dynamical systems have been considered. The difference of synergetic approach from the classical scientific methods is in identification of the fundamental role of self-organization in nonlinear dynamic systems, and it is necessary to keep the conceptual correspondence to the main qualities of self-organization: nonlinearity–open systems–coherence. Russian scientist A.A. Kolesnikov developed a novel synergetic approach based on the ideas of modern mathematics, cybernetics, and synergetics to the synthesis of control systems for nonlinear, multidimensional and multilinked dynamic systems of various natures. The synergetic approach to control theory (synergetic control theory) is a novel nonlinear control method where the nonlinearities of a system are considered in the control design and a systematic design procedures. On the other side, fractional calculus (FC) has a long history of three hundred years, over which a firm theoretical foundation has been established. All fractional operators consider the entire history of the process being considered, thus being able to model the non-local and distributed effects often encountered in natural and technical phenomena and they provide an excellent instrument for description of the memory, heredity, non-locality, self-similarity, and stochasticity of various materials and processes. Fractional dynamics can be encountered in various nonlinear dynamical systems such as visco-elastic materials, electrochemical processes, thermal systems, transmission and acoustics, chaos and fractals, biomechanical systems, and many others. The fractional dynamic systems with nonlinear control represent a relatively new class of applications of the FC which certified the FC as being a fundamental tool in describing the dynamics of complex systems as well as in advanced nonlinear control theory.
