Savelenko I. Automation of traction control systems with synchronous motors based on permanent magnets

The thesis is devoted to solving actual scientific task of developing the theory analysis and synthesis relay laws traction control systems, thus improving the energy efficiency of electric traction. The analysis methods for solving the problem of synthesis of ACS-based electric SМPM found that the most appropriate approach to the synthesis of optimal controls for electric relay based PMSМ approach is based on a switching properties of optimal control functions. Formalized problem optimal control relay regulators on the basis of the properties of functions optimal switching control, thus improving the energy efficiency of traction traction units based PMSМ and improve their static and dynamic characteristics. The computer model of automatic control by electric locomotive traction through which assessed the effectiveness of the proposed system of automatic control by computer simulation. Were done experimental study of the developed system of automatic control. The results of computer modeling, experimental investigation and feasibility study confirmed the effectiveness and feasibility of the proposed relay in the controls for ACS traction systems.
