Page 20 - Modern Control Systems

Preface
For example, the problem set for The Root Locus Method, Chapter 7 (see page
443) includes 28 exercises, 39 problems, 14 advanced problems, 14 design problems,
and 10 computer-based problems. The exercises permit the students to readily uti-
lize the concepts and methods introduced in each chapter by solving relatively
straightforward exercises before attempting the more complex problems. Answers
to one-third of the exercises are provided. The problems require an extension of the
concepts of the chapter to new situations. The advanced problems represent prob-
lems of increasing complexity. The design problems emphasize the design task; the
computer-based problems give the student practice with problem solving using
computers. In total, the book contains more than 1000 problems. The abundance of
problems of increasing complexity gives students confidence in their problem-
solving ability as they work their way from the exercises to the design and computer-
based problems. An instructor's manual, available to all adopters of the text for
course use, contains complete solutions to all end-of-chapter problems.
A set of m-files, the Modem Control Systems Toolbox, has been developed by
the authors to supplement the text. The m-files contain the scripts from each com-
puter-based example in the text. You may retrieve the m-files from the companion
website: www.pearsonhighered.com/dorf.

Design Emphasis without Compromising Basic Principles. The all-important topic
of design of real-world, complex control systems is a major theme throughout the
text. Emphasis on design for real-world applications addresses interest in design by
ABET and industry.
The design process consists of seven main building blocks that we arrange into
three groups:
1. Establishment of goals and variables to be controlled, and definition of
specifications (metrics) against which to measure performance
2. System definition and modeling
3. Control system design and integrated system simulation and analysis
In each chapter of this book, we highlight the connection between the design
process and the main topics of that chapter. The objective is to demonstrate differ-
ent aspects of the design process through illustrative examples. Various aspects of
the control system design process are illustrated in detail in the following examples:
Q smart grids (Section 1.9, page 28)
Q photovoltaic generators (Section 2.8, page 91)
a space station orientation modeling (Section 3.8. page 193)
Q blood pressure control during anesthesia (Section 4.8, page 259)
Q attitude control of an airplane (Section 5.9, page 346)
Q robot-controlled motorcycle (Section 6.5, page 406)
• wind turbine rotor speed control (Section 7.8, page 497)
Q maximum power pointing tracking (Section 8.6, page 583)
Q PID control of wind turbines (Section 9.8, page 674)
Q milling machine control system (Section 10.12, page 790)
