Summary: The designs of electric drives with the induction motor (IM) providing power saving capabilities and a negligible return action of the drive to the network will be investigated. Drive types, operation procedure, stability, and pulsating moments of the motor and the entire drive will be taken into account. Mathematical models and programs for the electric drive characteristics simulation will be made and voltage-current and power characteristics of controlled electric drives with IM will be analyzed. Designs and algorithms of the scalar and vector control of the moment and IM rotation speed will be studied. Mathematical models will be investigated and the software for the simulation of the switched reluctance motor and the controlled electric drive with this motor in both stationary and dynamic states of the drive will be developed. Designs and algorithms for controlling the moment and the rotation speed of electric drive with SRM, as well as the current-voltage and power conditions of SRM and electric drive with this motor will be investigated. The characteristics of IM and SRM as well as the characteristics of controlled electric drives with these motors will be comparatively investigated with the aim of discovering the applications for which the particular drive represents a better solution. The results of the theoretical research work will be tested by measurements.

Keywords: induction motor, switched reluctance motor, electric drives, simulations, microprocessor control systems, mathematical models, measurements

Research goals: Development of methods for the examination of the stationary and dynamic behavior of the IM and SRM drives. Improvement of the mathematical models, simulation programs and functional models (for the verification of the theoretical research results) of the motor and motor drives itself. Contribution to the creation of the integral, scientificly founded, theoretical bases for the development and design of induction (IM) and switched reluctance (SRM) motors for a modern drive, bases for the development and design of the drive power inverters and control circuits. Analysis of IM and SRM drive structures, that insure energy savings and negligible influence of the drives on the power network, considering drive type, torque ripple and stability of the motor and drive. Examination of the simpler and economical motor constructions, inverter structures and control systems of the general and special purpose SRM drives. Global goal is creation of the personnel, technical and technological base and the team of the assistants of the various specialties to overcome the modern solutions of the regulated motor drives.
