The course gives a brief overview of basic types of electric drives. It deals with drives with DC, asynchronous, synchronous and special motors including power electronic converters.Another topics include control strategies such as scalar, vector, direct, sensorless control of AC drives, pulse width modulation strategies and various load types. It is focused on understanding the physical nature of a given type of drive, general derivation of basic differential equations describing transient and steady states, and creating corresponding mathematical models of analyzed systems suitable for both off-line simulation and online-adapted dynamic and real-time control using the basis of modern microprocessor technology. Problems of operating states, sensors and diagnostics of electric drives are also discussed. Basic knowledge of mathematics, mechanics, kinematics, dynamics, theory of electromagnetic field, circuit theory and control theory are assumed.
