Geregelte Drehstromantriebe - Controlled AC Drives

The lecture is offerd in english. Bilingual lecture notes ( german / english ) are provided.

Die Vorlesung wird auf English angeboten. Es steht ein bilinguales Skript ( deutsch / englisch ) zur Verfügung. In Vorlesungen und Übungen können Sie Ihre Fragen auch gern auf Deutsch stellen. Auch die Prüfung kann in deutscher Sprache abgelegt werden.

The course introduces the principle of flux-oriented control of three-phase AC motors, which is today’s standard of electrical drives in industry. Unlike the course of the bachelor’s program focus is put on the dynamics behavior and on the control structures. As most important examples, the permanent magnet synchronous motor and the induction motor are treated.

Contents

• AC drives: Synchronous and induction motor (structure, basic physical effects, modelling, equivalent circuit diagrams, characteristic curves, operation areas)
• Speed and torque control
• Space vector theory (fundamental wave, coordinate transformation)
• Principles of flux-oriented control
• Closed-loop control of current, torque and speed, design methods
• Direct Torque Control (DTC)
• Observers
• Applications in industry, road and rail vehicles

Learning goal

• The students will understand the most important types of AC drives, their properties and should be able to select and to design such drives by themselves.
