At the end of the module students are able:

  • to remember the working principals of the most common electrical machine types.
  • to understand how modern drive systems can be modeled.
  • to distinguish between dynamic control strategies such as field-oriented and direct-torque control and their sensible applications.
  • to recall the requirements of the different machines concerning sensors and power electronics.
  • to choose electrical machines and converter topologies based on application requirements.
  • to design electric drive trains and their control.

Inhalte

Electrical drives are used in many different fields: at home, in industry and for transportation. Dental drills as well as hybrid or fully electric vehicles and ships are powered by electrical motors. The advantages of electrical drives are that electricity is applicable almost everywhere and comparatively easy to decentralize, power and velocity are easy to control, the maximum machine torque is available at zero speed and wear and maintenance costs are low. Particularly due to their high efficiency, electrical drives score well. Since electrical drives consume about 60% of all electrical energy used in industry and gain more and more importance in the field of personal mobility, a huge amount of energy can be saved by an intelligent control of electrical motors. The above mentioned control of electrical motors is the topic of the lecture Electrical Drives. Subsequent to a short introduction to the mechanics of rotating systems the control of all common electrical machines (DC, synchronous, induction and switched reluctance machine) is presented. The universal field oriented (UFO) concept is explained which demonstrates the concepts of modern vector control and exemplifies the seamless transition between so called stator flux and rotor flux oriented control techniques. This powerful tool is used for the development of flux oriented machine models of rotating field machines. These models form the basis of UFO vector control techniques which are covered extensively together with traditional drive concepts. Attention is also given to the dynamic modeling of Switched Reluctance (SR) drives, where a comprehensive set of modelling tools and control techniques is presented. The lecture should appeal to students who have a desire to understand the intricacies of modern electrical drives without loosing sight of the fundamental principles. It brings together the concepts of the ideal rotating transformer (IRTF) and UFO which allows a comprehensive and insightful analysis of AC electrical drives in terms of modeling and control. Extensive use is made of build and play modules which provide the student with the ability to interactively examine and understand the presented topics.
