Section Four – Systems and Controls
An overview of signals and systems is presented in this fourth section. Since there is a significant body
of readily-available material to the reader on the general subject of signals and systems, there is not an
overriding need to repeat that material here. Instead, the goal of this section is to present the relevant
aspects of signals and systems of special importance to the study of mechatronics. The section begins
with articles 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 H 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 section concludes with a chapter
on design optimization for mechatronic systems. The chapters, listed in order of appearance, are:

21. The Role of Controls in Mechatronics

Section Five – 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. The
last two sections of the Mechatronics Handbook are devoted to the topics of computers and software. In
