Abstract(s)
PID regulators are the backbone of most industrial control systems. The problem of deter-mining their parameters, then, is of great importance in the professional control domain. To simplify this task and reduce the time required for it, many PID regulators nowadays incor-porate autotuning capabilities, i.e. they are equipped with a mechanism capable of comput-ing the ‘correct’ parameters automatically when the regulator is connected to the field. Due to the importance of the problem, a very wide variety of PID autotuners have been developed and are currently available on the market. This monograph is aimed at control professionals who want to approach the problem of choosing and applying a PID autotuner in a knowledgeable and effective way. This goal is pursued by inducing an understanding of the theory of autotuner operation rather than by presenting an exhaustive menu of techniques and commercial products. As a consequence, this volume does not lead to a mere selection guide but to a set of concepts that, once mas-tered, allows the reader to evaluate the effectiveness of a specific industrial autotuner for a particular application. A significant space is also devoted to the review of PID control prin-ciples, essentially for less experienced readers. Some industrial products are presented, to il-lustrate how the concept introduced for classifying and selecting autotuners reflect in the real world, and samples of current research are given based on the authors’ experience.
