Leeb Abstract The increasingly wide availability of highly
capable power electronic drives has motivated an increased interest in actively
controlled electric machines over the last two decades. The successful
application of modern control techniques, including field-oriented control,
depends on an intimate knowledge of machine parameters and characteristics.
Lower shaft horsepower drives, for example, may exhibit a relatively speedy
decay of electrical transients in comparison to mechanical transient settling
times. In very large drives, the situation can be reversed. Carefully applied
computer-based tools for estimating machine and drive performance can remarkably
speed a designer's understanding of when different control and machine design
assumptions are applicable, and how gracefully these assumptions fail as
performance limits are approached. In this tutorial, we will review basic
modeling assumptions and techniques (DQ modeling) for electric machinery,
particularly in the context of the induction machine. We will focus on developing
simulation models appropriate for speedy computer analysis using tools like
MATLAB.
Biography Steven Leeb received his doctoral degree from the Massachusetts Institute of Technology in 1993 in Electrical Engineering and Computer Science. He has been a member of the M.I.T. faculty in the Department of Electrical Engineering and Computer Science since 1993. He currently serves as an associate professor in the Laboratory for Electromagnetic and Electronic Systems. Dr. Leeb is concerned with the design, analysis, development, and maintenance processes for all kinds of machinery with electrical actuators, sensors, or power electronic drives.
