Preface
AC motors play a major role in modern industrial applications.
Squirrel-cage induction motors (SCIMs) are probably the most
frequently used when compared to other AC motors because of
their low cost, ruggedness, and low maintenance.
The material presented in this book is organized into four
sections, covering the applications and structural properties of
induction motors (IMs), fault detection and diagnostics, control
strategies, and the more recently developed topology based on
the multiphase (more than three phases) induction motors.
This material should be of specific interest to engineers and
researchers who are engaged in the modeling, design, and
implementation of control algorithms applied to induction motors
and, more generally, to readers broadly interested in nonlinear
control, health condition monitoring, and fault diagnosis.

Abstract
Wind power is the fastest growing renewable energy and is promising as the number
one source of clean energy in the near future. Among various generators used to
convert wind energy, the induction generator has attracted more attention due to its
lower cost, lower requirement of maintenance, variable speed, higher energy capture
efficiency, and improved power quality [1-2]. Generally, there are two types of
induction generators widely used in wind power systems – Squirrel-Cage Induction
Generator (SCIG) and Doubly-Fed Induction Generator (DFIG). The straightforward
power conversion technique using SCIG is widely accepted in fixed-speed applica‐
tions with less emphasis on the high efficiency and control of power flow. However,
such direct connection with grid would allow the speed to vary in a very narrow range
and thus limit the wind turbine utilization and power output. Another major problem
with SCIG wind system is the source of reactive power; that is, an external reactive
power compensator is required to hold distribution line voltage and prevent whole
system from overload. On the other hand, the DFIG with variable-speed ability has
higher energy capture efficiency and improved power quality, and thus dominates
the large-scale power conversion applications. With the advent of power electronics
techniques, a back-to-back converter, which consists of two bidirectional converters
and a dc-link, acts as an optimal operation tracking interface between DFIG and loads
[3-5]. Field orientation control (FOC) is applied to both rotor- and stator-side
converters to achieve desirable control on voltage and power [6,7].
In this chapter, a brief introduction of wind power system is presented first, which is
followed by introduction of SCIG and DFIG from aspects of modeling and control.
The basic FOC algorithm is derived based on DFIG model in dq reference frame. At
last, the power generation efficiency is considered through different Maximum Power
Point Tracking (MPPT) methods that have attracted a lot of attention in the variable-
