Tuning of Industrial Control Systems, by A.B. Corripio. Instrument Society of
America, North Carolina, USA (1990). 279 pp. ISBN 1-55617-233-8.
This book is number 16 in a series of books which first appeared in 1981. Each
book is an Independent Learning Module for a particular topic in the field of
instrumentation and process control. The earlier volumes covered the more traditional
or fundamental subjects in the field, the more recent volumes have dealt with
emerging areas/technologies.All the books in this series are intended for self-study
and are presented so that they can be used independently of other texts and references.
There is a danger in this approach of thinking that this is all there is to know, rather
than appreciating that the text is providing basic knowledge and information.
However, this book does its intended task well and will be a useful and informative
source of information to many practicing engineers and students. There is a need for
this type of text in many areas of engineering, not only the newer emerging
technologies but also as reference texts for some of the older more established areas.
It is a pity that some other professional bodies don’t promote this type of publication.
The book is very well written with a high standard of presentation, it is easy to
read and provides a good introduction to an important aspect of the installation and
design of automatic control systems, namely tuning. Also included in an appendix is
a BASIC program for tuning computer control algorithms which many readers will
find useful. The material is well presented so that the reader gets a very clear picture
of what is required and how the book is organised. It states as a guide in the
Introduction that 3040 hours are required to complete this module depending upon
prior knowledge and experience.
Each chapter contains an introductory paragraph, a set of learning objectives, then
the main material presented in a clear and well written form including some examples,
a summary, exercises, and references (in most chapters). There is also an appendix of
suggested readings and study materials. At the end of the book are solutions to all the
exercises which is a good, if not essential, feature of a self-study text. The chapters
are organised and presented in such a way that the reader can easily appreciate what
is important, and what should be known at the end of each unidchapter.
Units 2-4 cover the fundamental concepts of tuning, namely the modes of
feedback control, the characterization and measurement of process dynamic response,
the selection of controller performance, and the adjustment of the tuning parameters.
Unit 5 is concerned with selection of controller modes and tuning parameters for
some typical control loops. Unit 6 is devoted to the specific problem of tuning
computer- and microprocessor-based control algorithms. The latter part of the book
(units 7-10) demonstrates how to tune the more advanced industrial control strategies,
namely cascade, feedforward, multivariable, and adaptive control systems. The book
concentrates on how the tuning methods relate to the dynamic characteristics of the
controlled process. The aim is to provide insight on the tuning procedures rather than
a mass of information to be memorised. Techniques based on frequency response,
root locus, and state space analysis are not included. My only reservation is that the
inclusion of more worked examples would have been a valuable addition. Without a
teachedtutor, an independent learning module must rely heavily upon examples to
illustrate the use of the text material.
In summary, I highly recommend this book to students (to supplement formal
taught courses in process control) and to practicing engineers. I hope that the reader
does not assume that this is the whole story/extent of knowledge on this topic. It
achieves its objectives and is a valuable and useful learning module. The aim is to
produce four such volumes per year, I eagerly look forward to the arrival of the
subsequent modules.

Boilers, Evaporators and Condensers, by S. Kacak. John Wiley and Sons, Inc.,
New York, USA (1991). 835 pp. ISBN 0471-62170-6.
This is an excellent book that has been very thoroughly and professionally edited.
I have seen many multi-authored texts under the overall direction of an editor that
have still needed tidying up to make the final copy appear as a uniform book rather
than a collection of paperskhapters independently thrown together. Thankfully this
book does not fall into this category. It is well edited and despite separate
nomenclatures for each chapter, which is probably inevitable, it reads as a carefully
thought out treatise on the subject. I found very few typographical (or other) mistakes
while performing this review. The coherence of the book is probably helped by the
fact that Professor Kacak wrote the Introduction (Chapter 1) and also co- authored
Chapters 2, 3 and 4. There is often bias against edited books (even Perry), the
detractors claiming that a single author presents a more balanced and consistent
approach to the material. There is some merit in this argument, however it also makes
sense to use the expertise of leaders in particular fields especially for a topic as large
as Boilers, Evaporators and Condensers.
The book consists of 13 chapters, plus an appendix of thermophysical properties.
There is a useful index, although an author index would have been appreciated its
omission is not serious. Also included are a good number of worked
examples/calculations illustrating the design methods discussed. This book should
become an essential reference text for undergraduate engineering students to
compliment their basic heat transfer units. It will be an invaluable reference source
when faced with the design of systems involving change of phase. Evaporator design
is already covered quite well in the literature, but boiling and condensation design
