Mokin O. Models' parameter identification and system's modes optimization for tram's electric drive with the direct current propulsion engine

The system of coupler electric drive of tram's electrotechnical complex. The minimization of electric energy losses in the system of tram's electric drive with series excitation direct current engines (SEDCE). The methodology of mathematical analysis and identification theory, variational methods of optimal process's theory, electrotechnical and electric drive's theories, automatic control's theory. There had been made the linear-parabolic mathematic model of the SEDCE magnetize curve. There had been suggested the method for experimental identification of the tram's electric drive dynamic model system. The optimal laws of the armature current change and the rotation angular velocity of SEDCE rotor shaft in the tram's electric drive with transistor control for the mode of stable load and of stable under- and overloading are obtained. The results, obtained in the thesis, introduced into the educational process in Vinnytsia National Technical University and into the practical activity of the Vinnytsia enterprise "Trams and Trolleybuses Administration". The management of urban electric transport.
