This practical level textbook from ISA teaches the practice of process control for the processing industries. It stresses the study of real, imperfect processes rather than systems theoroy, and gives guidance on how you can best apply your experience, knowledge and intuition to improve the control of your processes.
The book summarizes the general characteristics of processes and control loops, and discusses feedback control and its nuances. The laboratory exercises in PC-ControLAB correlate well with topics in the textbook. Use of the two together enhances comprehension and retention of the material.
