CONTENT

In this course, we will use a new but thoroughly tested approach to understanding the physical basis on which ac and dc machines operate, thus allowing a clear understanding of how they ought to be controlled in electric drives for optimum performance in vector control applications. This, coupled with the building-block approach to clearly understanding switch-mode power electronics used in modern-day drives allows us to discuss the entire subject of electric drives for motion control in a very short time.

This physical-based approach, unlike highly mathematical or circuit-oriented approaches of the previous century, has been developed over the past eight years and is described in the textbook "Electric Drives: An Integrative Approach" by Ned Mohan available from www.mnpere.com. (This book is reviewed by Professor Marian P. Kazmierkowski in the IEEE Industrial Electronics Society Newsletter, which is available at the following website: http://sant.bradley.edu/~ienews/00_3/edrives.html.)

This physical understanding is then extended to describe vector control and sensor-less direct torque control (DTC) of induction motor drives. We will show modeling of these drives using SIMULINK™. These later topics are extracted from the book "Advanced Electric Drives: Analysis, Control and Modeling using SIMULINK" by Ned Mohan in print now and available in August 2001.

Detailed course notes will be provided.

BIOGRAPHY OF NED MOHAN

Dr. Ned Mohan has been with the University of Minnesota since 1976 where he is a professor of electrical and computer engineering and holds Oscar A. Schott Chair in power electronics. He has received the Distinguished Teaching Award from the University of Minnesota.

He is a lead co-author of a widely used textbook on Power Electronics, which has also been translated into several languages (Chinese, Greek, Korean and soon in Turkish). Recently, he has authored a new textbook "Electric Drives: An Integrative Approach", which in six short months subsequent to its publication has been adopted as a textbook at fifteen major universities.

Recently, in addition to his research activities, he is developing educational material and laboratories for courses in power electronics and motor drives.

Prof. Mohan is a Fellow of the IEEE.
