Chapters 10 and 11 focus on sinus oidal frequency analysis and design. Chapter
10, like Chapter 8, covers basic concepts for stability, transient response, and steady-
state-error analysis. However, Nyquist and Bode methods are used in place of root
locus. Chapter 11, like Chapter 9, covers the design of compensators, but from the
point of view of sinusoidal frequency techniques rather than root locus.
An introduction to state-space design and digital control systems analysis and
design completes the text in Chapters 12 and 13, respectively. Although these
chapters can be used as an introduction for students who will be continuing their
study of control systems engineering, they are useful by themselves and as a
supplement to the discussion of analysis and design in the previous chapters. The
subject matter cannot be given a comprehensive treatment in two chapters, but the
emphasis is clearly outlined and logically linked to the rest of the book.
Acknowledgments
The author would like to ackn owledge the contributions of faculty and students, both
at California State Polytechnic University, Pomona, and across the country, whose
suggestions through all editions have made a positive impact on the new edition.
I am deeply indebted to my colleagues, Elhami T. Ibrahim, Salomon Oldak,
and Norali Pernalete at California State Polytechnic University, Pomona for author-
ing the creative new problems you will find at the end of every chapter. Dr. Pernalete
created the LabVIEW experiments and problems you will find in this new edition.
The new prog ressive problem, hyb rid vehicle, that is at the end of every chapter is the
creation of Dr Ibrahim. In addition to his busy schedu le as Electrical and Computer
Engineering Department Chairman and author of many of the new problems,
Professor Oldak also error checked new additions to the book and prevented
glitches from ever reaching you, the reader.
I would like to express my appreciation to contributors to this sixth edition who
participated in reviews, accuracy checking, surveys, or focus groups. They are: Jorge
Aravena, Louisiana State University; Kurt Behpour, Cal Poly San Luis Obispo; Bill
Diong, Texas Christian University; Sam Gucc ione, Eastern Illinois University;
Pushkin Kachroo, Virginia Tech; Dmitriy Kalantarov, Cal State San Diego; Kamran
Iqbal, University of Arkansas, Little Rock; Pushkin Kachroo, Virginia Tech; Kevin
Lynch, Northwestern University; Tesfay Meressi, University of Massachusetts,
Dartmouth; Luai Najim, University of Alabama at Birmingham; Dalton Nelson,
University of Alabama at Birmingham; Marcio S. de Queiroz, Louisiana State
University; John Ridgely, Cal Poly San Luis Obispo; John Schmitt, Oregon State
University; Lili Tabrizi, California State University, Los Angeles; Raman Unnik-
rishnan, Cal State Fullerton; Stephen Williams, Milw aukee School of Engineering;
Jiann-Shiou Yang, University of Minnesota, Duluth; and Ryan Zurakowski, Uni-
versity of Delaware.
The author would like to thank John Wiley & Sons, Inc. and its staff for once
again providing professional support for this project through all phases of its
development. Specifically, the following are due recognition for their contributions:
Don Fowler, Vice President and Publisher, who gave full corpo rate support to the
project; Daniel Sayre, Publisher, with whom I worke d closely and who provided
guidance and leadership throughout the development of the sixth edition; and Katie
Singleton, Senior Editorial Assistant, who was always there to answer my questions
and respond to my concerns in a professional manner. There are many others who
