Havryliuk S. The system of automatic control of gearless asynchronous electric drives with aerodynamic load

The object of research: processes of electromechanical energy conversion in gearless electric drives. The purpose of work: increase accuracy of control and dynamic properties of gearless electric drives with stochastically changing aerodynamic load by creating automatic combined control systems based on indirect load torque measurement and two-channel control systems with electromechanical differential. The research methods are based on the use of the fundamental provisions of electrodynamics and theoretical electrical engineering, the theory of electric machines, the theory of electric drives, the theory of automatic control, theoretical mechanics, modelling in Matlab. Theoretical and practical results and innovations: the actual scientific problem of creation the automatic control systems of the gearless electric drives with aerodynamic load, with the expanded range of regulation of speed and with the improved control quality, is solved. The design of an electric machine with windings on the stator and rotor, mechanical separation of the main and intermediate rotors, which was the basis of gearless electromechanical differential and allowed to implement two-channel control without the use of mechanical gears, has been developed. A subject degree of introduction: the main results of the work are implemented at Ltd. «Scientific and Technical Firm «TEMS » and at Ltd. «SPE «Technoservicepryvod». Effectiveness of implantation: a significant technical and operating effect is obtained, which is to improve the quality of control systems of gearless electric drives (increase the accuracy of speed control and expand the range of speed regulation of the electric drives). Sphere of use: gearless electromechanical systems.
