Rudnev E. Development and research of robust control systems of electric AC drives with synchronous motors

Object of study - the dynamic processes in synchronous drive at different combinations of set and disturbances. The purpose of research - improving the accuracy and quality of the stabilization variable speed AC drives with synchronous motors, operating with incomplete information about the object and with the parametric uncertainty means H-robust control theory. Research methods and equipment - methods of automatic and robust control, and the theory of electric and electric vehicles. Theoretical and practical results - to develop practical recommendations for the synthesis of robust control, which can be used in the design of electric AC and DC with incomplete information about the object, given its parametric uncertainty. Novelty - received scientific evidence synthesis capabilities management system with the required accuracy rate stability and low sensitivity to parametric and coordinate perturbations acting on the control object, the mathematical description of the one masses and two masses synchronous drive with the uncertainties presented as a linear fractional transformation, further developed methods of synthesis of robust controllers for speed control of synchronous motors, in particular, proved that the weight functions that are included in the consolidated entity for the synthesis of robust controller is the "authority / settings" quality characteristics of a closed robust management system. The degree of implementation - PJSC "Alchevsk Iron-and-Steel Works" (Alchevsk). Applications - machine industry.
