MIT-Aston Summer Course 2016

Topic: Design of Motors, Generators, & Drive Systems
Date: 19th-24th June 2016
Venue: Conference Aston, Aston University, Birmingham

Construction of aggressive, high-performance motor drives requires a detailed understanding of machine characteristics and associated interactions with power electronic drives.  The successful application of modern control techniques, such as field-oriented control, depends critically 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 comparision to mechanical transient settling times.  In very large drives, the situation can be reversed.  Even for drives employing machines of the same general type, appropriate analytical approximations, thermal management and modeling, control techniques, and transient performance and disturbance rejection for low and for high power drives may therefore be very different.  Computer-based tools for estimating machine parameters and 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 course, fundamental principles of energy conversion, applicable to all types of electric machinery, are first reviewed to provide analytical foundations for understanding all types of drives. The specific principals of the basic machine types, including synchronous, induction and variable reluctance machines, are then introduced.  Extensive use of computer-based analysis tools will be made as the major classes of machines and their physical basis for operation are reviewed.  Next, control strategies for the different machine types will be discussed, all with  use of computer-based simulation tools. Throughout the course, performance considerations, trade-offs, and different design approaches will be presented. Extensive ``hands-on'' exposure will be provided through computer based laboratory exercises.
