This book is about the techniques of modeling and simulating electric machinery. It
evolved from a graduate-level course in simulation at Purdue that is aimed at introducing
students to the modeling of power components and to using computer simulation as a toot
for conducting transient and control studies. Simulation can be especially helpful in
gaining insights to the dynamic behavior and interactions that are often not readily apparent
from reading theory. Next to having an actual system to experiment on, simulation is often
chosen by engineers to study transient and control performance or to test conceptual
designs. Its use in teaching is growing now that inexpensive and powerful personal
computers with simulation capabilities previously available only in specialized facilities are
widely accessible to students.
