Preface
According to the original definition of mechatronics proposed by the Yasakawa Electric Company and
the definitions that have appeared since, many of the engineering products designed and manufactured
in the last 30 years integrating mechanical and electrical systems can be classified as mechatronic systems.
Yet many of the engineers and researchers responsible for those products were never formally trained in
mechatronics per se. The Mechatronics Handbook, 2nd Edition can serve as a reference resource for those
very same design engineers to help connect their everyday experience in design with the vibrant field of
mechatronics.
The Handbook of Mechatronics was originally a single-volume reference book offering a thorough
coverage of the field of mechatronics. With the need to present new material covering the rapid changes
in technology, especially in the area of computers and software, the single-volume reference book quickly
became unwieldy. There is too much material to cover in a single book. The topical coverage in the
Mechatronics Handbook, 2nd Edition is presented here in two books covering Mechatronic Systems, Sensors,
and Actuators: Fundamentals and Modeling and Mechatronic System Control, Logic, and Data Acquisition.
These two books are intended for use in research and development departments in academia, government,
and industry, and as a reference source in university libraries. They can also be used as a resource for
scholars interested in understanding and explaining the engineering design process.
As the historical divisions between the various branches of engineering and computer science become
less clearly defined, we may well find that the mechatronics specialty provides a roadmap for nontradi-
tional engineering students studying within the traditional structure of most engineering colleges. It is
evident that there is an expansion of mechatronics laboratories and classes in the university environment
worldwide. This fact is reflected in the list of contributors to these books, including an international
group of academicians and engineers representing 13 countries. It is hoped that the books comprising
the Mechatronics Handbook, 2nd Edition can serve the world community as the definitive reference source
in mechatronics.

Section I—Mechatronic System Control
Since there is a significant body of readily available material to the reader on the general subject of signals
and systems, there is no overriding need to repeat that material here. Instead, the goal of this book is to
present the relevant aspects of signals and systems of special importance to the study of mechatronics.
The book begins with chapters on the role of control in mechatronics and on the role of modeling in
mechatronic design. These chapters set the stage for the more fundamental discussions on signals and
systems comprising the bulk of the material in this section. Modern aspects of control design using
optimization techniques from H2 theory, adaptive and nonlinear control, neural networks, and fuzzy
systems are also included as they play an important role in modern engineering system design. The book
includes chapters on design optimization for mechatronic systems, and real-time monitoring and control.
The chapters, listed in order of appearance, are
1. The Role of Controls in Mechatronics
2. The Role of Modeling in Mechatronics Design
3. Signals and Systems
3.1 Continuous- and Discrete-Time Signals
3.2 z Transforms and Digital Systems
3.3 Continuous- and Discrete-Time State-Space Models
3.4 Transfer Functions and Laplace Transforms

Section II—Computers and Logic Systems
The development of the computer, and then the microcomputer, embedded computers, and associated
information technologies and software advances, has impacted the world in a profound manner. This is
especially true in mechatronics where the integration of computers with electromechanical systems has
led to a new generation of smart products. The future is filled with promise of better and more intelligent
products resulting from continued improvements in computer technology and software engineering. In
this section, the focus is on computer hardware and associated issues of logic, communication, network-
ing, architecture, fault analysis, embedded computers, and programmable logic controllers. The chapters,
listed in order of appearance, are
18. Introduction to Computers and Logic Systems
19. Digital Logic Concepts and Combinational Logic Design
20. System Interfaces
21. Communications and Computer Networks
22. Fault Analysis in Mechatronic Systems
23. Logic System Design
