This abstract is for the 3rd edition
which is the latest edition of this book title. This book was written
by the famous professors in the automatic control field. Both of the
authors are from Department of Automatic Control, Lund Institute of
Technology, Sweden. This book may be used for the early course in
automatic control; however, I do not recommend. This book is a good one
for the person who has some experiences and understanding about the
basic control theory, especially in continuous control theory. Some
basic knowledge about modern control theory such as state-space design
method, pole-placement method, observability and controllability, etc.
is also necessary for pursuing with this text book.
There is also a web-based supplement (for complete solutions of the
problems in the book and some programs for MATLAB) at
http://www.control.lth.se; see Education/Computer-Controlled Systems.
Contents of this book are comprised of the followings.
Chapter 1 Computer Control
Generally state about the elements of computer-controlled system and
computer-control theory. AD, DA are also described with some
Chapter 2 Discrete-Time Systems
Explain the basic of discrete time system which is the foundation for
digital control design. Examples are easy to understand and follow.
Chapter 3 Analysis of Discrete-Time Systems
Stability and robustness are analysed. Contrrollability, reachability,
observability, and detectability are described. Practical aspects of
choice of the sampling period are presented.
Chapter 4 Pole-Placement Design: A State-Space Approach
Clear and easy to understand for the explanation of the design method and some practical aspects.
Chapter 5 Pole-Placement Design: A Polynomial Approach
Some details about the polynomial approach are not practical and obscured.
Chapter 6 Design: An Overview
This chapter reviews the control problem in a wider aspect and especially in practical aspect.
Chapter 7 Process-Oriented Models
Aliasing or frequency folding is described with counter measure in
practical application. Frequency response of the discrete control
system is explained.
Chapter 8 Approximating Continuous-Time Controllers
Explain how to implement the discrete (digital) controller when the designer has the solution of the continuous controller.
Chapter 9 Implementation of Digital Controllers
Practical aspect in implementing the digital controller is explained.
Algorithm in programming is also recommended. Prefiltering and
computational delay effect is described. Antiwindup technique for
nonlinear actuator is introduced. Effects of roundoff and quantization
are also profoundly explained.
Chapter 10 Disturbance Models
Disturbance model and reduction of the effect of the disturbance is introduced. Stochastic models of disturbances are explained.
Chapter 11 Optimal Design Methods: A State-Space Method
Advanced control design, optimal design method, is introduced with some
difficulties for understand. LQG (Linear Quadratic Gaussian) is also
Chapter 12 Optimal Design Methods: A Polynomial Approach
This chapter is also for optimal design method by using polynomial
approach. The reader should have some knowledge about the control
system designed by polynomial approach and optimal control.
Chapter 13 Identification
System identification and mathematical model building for the black box
system are introduced. This chapter is also one of the difficult to
understand chapters in this book. The reader should have knowledge
about the system identification, parameter estimation, least square
As a conclusion, this book is one of the best text book on digital
(discrete) control system and should have it in hand. However, this
book should not be the first book to study the topic about the
automatic control. I rank this book for the middle-level reader who has
some experiences or knowledge about the basic of the automatic controool
system and some design method in classical and modern control system.
