P
rofessors Uttam Ray Chaudhuri from Calcutta
University (Kolkata, India; www.caluniv.ac.in) and
Uptal Ray Chaudhuri from Jadavpur University
(Kolkata, India; www.jadavpur.edu) have authored a
preparatory textbook on automatic process control. The
target audience for the book seems to be students in an
introductory process-control course.
After an opening introduction, the book offers an openloop-system
dynamic analysis using Laplace analysis and
continuous time differential equations. This analysis is
followed by material on closed-loop-control dynamic analysis
and PID (proportional-integral-derivative) tuning. The
book includes a chapter on advanced single-loop regulatory
control techniques, such as cascade, feed-forward,
adaptive and fuzzy logic, among others, as well as a chapter
on computer control.
The book comes with a CD
containing a software simulation
package that permits
experimentation with the different
techniques. The book also
includes a comprehensive guide
to the simulation system along
with suggested exercises.
A particularly strong point of the book is an extensive
set of worked examples in each chapter. The book also
includes an appendix containing problems and worked
solutions in process control from previous versions of the
Indian Graduate Aptitude Test in Engineering (GATE).
Some suggestions for the next version of the book include
the following. The preface states that " cost of controlling
instruments at a plant is about 40-60% of the
initial investment of the plant. " Automation costs for large
continuous-process plants in the chemical process industries
(CPI) actually are typically 3-5% of the total capital
investment. Also, the photographic reproductions in the
book are of low quality and difficult to interpret.
While practitioners may have differing opinions on
the proper approach to PID tuning, there are much
more widely accepted and newer methodologies than the
Ziegler-Nichols and Cohen-Coon techniques presented
