Yablon' V. Synthesis of relay systems of following eleсtric drive of high precision with low sensivity to parameter and coordinate disturbances

The aim of the dissertation is development of methods of synthesis and ways of practical realization of systems of following electric drive with relay control, which ensure high precision of reproduction of prescribed movement trajectories in conditions of wide-spectrum action of destabilizing factors.In the dissertation there is an application of methods of optimum, modal and adaptable control theory, method of invariance theory. Experimental researches were carried out with application of numerical modeling methods and laboratory-and-stand test.The practical significance of the dissertation's results is in working out the method of synthesis of relay control systems of following electric drive of heightened precision; in working out the algorithms, which allow to construct electromechanical systems with low sensitivity to parameter and coordinate perturbations.The scientific significance of the dissertation is in further development of automatic control theory in the part of construction of analogous and digital following systems of high precision with low sensitivity to perturbations by means of structure-algorithmic synthesis of relay regulators, working in zero-overshoot response.The field of application of considered electromechanical systems is specialized precise following systems of electric drive of antenna assemblies, telescopes, feeders of machines, robots.
