Recently, a great deal of effort has been dedicated to capitalising on advances in mathematical control theory in conjunction with tried-and-tested classical control structures particularly with regard to the enhanced robustness and tighter control of modern PID controllers. Much of the research in this field and that of the operational autonomy of PID controllers has already been translated into useful new functions for industrial controllers. This book covers the important knowledge relating to the background, application, and design of, and advances in PID controllers in a unified and comprehensive treatment including:
Evolution and components of PID controllers
Classical and Modern PID controller design
Automatic Tuning
Multi-loop Control
Practical issues concerned with PID control
The book is intended to be useful to a wide spectrum of readers interested in PID control ranging from practising technicians and engineers to graduate and undergraduate students.

PID control has a long history and widespread use in engineering The subject is covered comprehensively and in depth from its classical to its modern aspects
