Bovduj I. Synthesis of optimal control by electric drive based analytical models nonlinear load

Of research processes are an object in the systems of management by the electromechanics systems with analytical nonlinearities taking into account the resilient elements and nonlinear dependences of external friction. Of the thesis for technical sciences candidate's degree an improvement is a target of the systems of management by the electromechanics systems with analytical nonlinearities for the rise of exactness and reduction of the negative influencing of nonlinear and resilient elements of objects on the dynamic descriptions of the electromechanics systems. Methods of research: the construction of mathematical models of the nonlinear electromechanics systems as objects of management is executed on the basis of theory of electricdrive taking into account the resilient elements. Theoretical results: first offered systems of management by electricdrives on the basis of nonlinear optimum regulators and nonlinear observers of state; mathematical models are created of nonlinear electricdrives with the difficult kinematics copulas as one-, two- and threemass electromechanics systems taking into account the analytical dependences of the nonlinear external load; methods are developed of synthesis of the systems of management by electricdrives with the analytical models of the nonlinear load on the basis of nonlinear optimum regulators and nonlinear optimum observers of state. The practical value of the got results consists in development of new nonlinear systems of management by electricdrives of securing the high-quality adjusting. A scientific novelty of work consists in the theoretical development and generalization of method of synthesis of the systems of optimum management by electricdrives on the basis of analytical models of the nonlinear load, which allowed to promote exactness and suit, which are produced to the systems of management by electricdrives. Results, got in The thesis for technical sciences candidate's degree are inculcated on the State enterprise the Science-plant corporation the "Kiev institute of automation" and in Magnetism of Technical Objects Science and Technology Center of the National Academy of Sciences of Ukraine at implementation of research work of department order of National Academy of Sciences of Ukraine the "Scientific bases of synthesis of the multichannel systems of high-fidelity management by objects with the nonlinear and resilient elements". Sphere of the use in practice of creation of modern new, and modernizations of the existing, high-fidelity systems of management by electricdrives including: at creation of the high-fidelity systems of aiming and stabilization of armament of objects of armour engineering; at production of the high-fidelity systems of aiming and stabilization of armament of objects of armour engineering; for upgrading technological processes of rolling production.
