ES4F2-15 Control of Electrical Drives
ES4F2-15 Control of Electrical Drives
Modern electrical drives are complex electromechanical systems combining electrical machines, power electronic converters, control and protection circuits. The aim of the module is to develop an advanced understanding and systematic analysis and design skills on integration of electrical machines and power electronics into up-to-date electrical drives with predefined and required control quality. It will include development of conceptual functional block diagrams of the electrical drives, their mathematical modelling and simulation, systematic design of required controllers, advanced analysis of steady state and dynamic drives’ characteristics, electrical schematics and modern practical implementation.
