Nikitina T. Multicriterion synthesis of nonlinear robust control by multimass systems on the basis of analytical models of the nonlinear loading

A research object - are processes in the multimass electromechanics systems of automatic control. A research aim is a ground and development of perspective conception of multicriterion synthesis of robust control by the multimass electromechanics systems on the basis of theoretical development and generalization of mathematical models and methods of vector optimization of the synthesized systems indexes quality. Research methods and apparatus are fundamental positions of automatic control theory, state space methods , methods of robust control analysis, methods of mathematical design, robust control analysis and synthesis system methods, simulation techniques. Theoretical results - the task of multicriterion synthesis of nonlinear robust control is first formalized by the multimass systems, that allows to satisfy to the various requirements in the different modes. The equivalence of decision of problem of multicriterion synthesis of nonlinear robust control is shown on the basis of conception functionally to plural belonging of state vector to the decision of Hamilton-Jacobi-Bellman-Isaacs equation. The practical value of performances consists in creation and practical realization of methodology of multicriterion optimization of quality indexes of the multimass systems with difficult kinematics connections, the distinguishing features of which are wide possibilities of effective formalization of tasks of optimization, forming of the desired values of quality indexes, synthesis of high order systems with many varied parameters. The novelty of work consists in development and ground of perspective conception of multicriterion synthesis of robust control by multimass electromechanics systems on the basis of theoretical development and generalization of models and methods of vectorial optimization of quality indexes. A degree of introduction is the results of scientific developments are inculcated in practice of planning of the difficult electromechanics and electrohydraulic systems with difficult kinematics connections in a scientific-production corporation "The Kyiv institute of automation", in the Lvov radiotechnical institute, on the enterprise of "HARTRON -ARCOS" and at the Kharkiv armored repair plant. Materials of dissertation are used in lecture courses the "Optimal and conflictguided systems" and "control systems theory" on the systems analysis and control department of NTU "KhPI". Sphere of the use - in practice of creation of modern new and modernisation of existent highfidelity control system by multimass electromechanics systems with unexactly preset parameter of plant.
