Open enrollment training
The overall aim of the course is to provide an understanding of the design, modeling and assessments of electric drive systems, primarily for a hybrid or electric vehicle application. The course will provide a deep understanding of electric machines: steady-state, and (for the dc-, induction and the permanent magnet synchronous machine) dynamic performance with speed and current control including relevant theory. The dc motor drive is used as a model example for other drives. Power electronics converters and control theory relevant to the electric drive systems in hybrid or electric vehicles are also treated. Further, an electric vehicle propulsion drive system is introduced and modeled, using field vector control, including vehicle dynamics, and performing simulations after a given drive cycle. The student is encouraged to consider environmental aspects, such as energy-efficient drive systems.
After the course the participant will be able to:
- Describe the steps required for the design and implementation of an electric drive system and the demands on the electrical machine, primarily for a hybrid or electric vehicle application.
- Describe the assessments of the treated electric machines (mentioned below), the way of operation, relevant models, and general performance such as torque-speed curves.
- Recognize the appearance of the different machine types and know what the main parts look like and what kind of materialsthat can be used.
- Describe the performance and topology of power electronic converters, primarily for an electric vehicle application. Also describe how pulse width modulation works and can be used.
- Understand and follow safety instructions for the drive system lab used in the course.
- Describe the dynamic performance of the dc machine, the induction machine and the permanent magnet synchronous
machine with the coupled electric and mechanic equations.
- Use the relevant models and perform simulations with Matlab/Simulink on direct start, current and speed control of the dc machine, connected to the supply via a thyristor converter (assumed ideal).
- Use the relevant models and perform simulations with Matlab/Simulink on vector field torque control of the permanent
magnet synchronous machine.
- Compare simulations and experimental findings and document and present the work in a written report.
- Choose the relevant (environmental friendly)drive system for an application with given specifications especially for hybrid or electric vehicles (like high speed, space requirements, price, efficiency, fault tolerance etc).
