As the field of
process control has matured over the last 30 years, it has become one of the core areas in
chemical engineering along with thermodynamics,
heat transfer,
mass transfer,
fluid mechanics, and reactor kinetics. Any chemical engineering. graduate should have some knowledge not only of these traditional areas but also of the fundamentals of process control. For those of us who have been part of this period of development, the attainment of parity with the traditional areas has been long overdue. The literature in process control is enormous: over a dozen textbooks and thousands of papers have been published during the last three decades. This body of knowledge has become so large that it is impossible to cover it all at the
undergraduate level. Therefore, we present in this book only those topics we feel are essential for gaining an understanding of the basic principles of process control.
