Mokin O. The problem of identification of optimal motion models of nonlinear distributed dynamical systems of class of multimass electric vehicles and methodology for its solution

The object of the research are processes in nonlinear distributed dynamical systems of class of multimass electric vehicles (NDDSCMEV) during the movement on surfaces with complex relief; the objective of the research is the creation of methodology for solving scientific problems of NDDSCMEV model identification while driving on surfaces with complex relief, optimal by the criterion of minimum energy consumption in terms of the restrictions stipulated for by the requirements of operational safety and suitability for solving engineering problems of energy efficiency in the operation of the electric energy transport; methods of the research are based on the use of theoretical mechanics, the differential and integral equations, the variational methods of optimization, functional analysis, the principles of electrical engineering, theory of electric drive, theory of automated control; theoretical results - in the structure of the created methodology for the solution of issues of identification of mathematical models of optimal motion on surfaces with complex relief for a specific class of dynamical systems, there had been developed for the first time: a method of integrally-harmonic identification of NDDSCMEV, which allows to obtain the basic mathematical models of these systems which are suitable for the synthesis of optimal movement models, the method for the determination of the character and order of NDDSCMEV nonlinearity that enables to create the structures of the basic mathematical models of these systems, mathematical models of NDDSCMEV motion on surfaces with complex relief optimal by the criterion of minimum energy consumption, methods for determining the boundary conditions for the optimization problem of NDDSCMEV motion on a way that is curved in the horizontal or vertical plane, a modification of the Ritz method, using the algorithms of which there takes place the synthesis of optimal movement models of this class of dynamical systems by using Hilbert space; the practical results - the minimization of the energy consumption by electric vehicles during their movement along the routes. The degree of implementation - the results obtained in the thesis are implemented into the training process in Vinnytsia National Technical University, and accepted for the implementation by the UC "Vinytsia Tram and Trolleybus Administration", LTD "Zhmerinka Enterprise "Express"", Locomotive Depot of the st. Zhmerynka DGTO South-Western Railway Company and the "ATE Slobodyanyuk" (Vinnytsia). The sphere of application - dynamical systems of class of multimass electric vehicles.
