Preface

This book focuses on the basics of process control, process identification, PID controllers and autotuning. Our objective is to enable students and engineers who are not familiar with these topics to understand the basic concepts of feedback control, process identification, autotuning and design of real feedback controllers (especially PID controllers).

Parts One and Two are aimed at undergraduate students who have not taken any courses on process control. Parts Three and Four are appropriate for graduate students and control engineers who want to design real feedback controllers or perform research on process identification and autotuning. Parts One and Two introduce the basics of process control and dynamics, the analysis tools (Bode plot, Nyquist plot) to characterize the dynamics of the process, PID controllers and tuning, and advanced control strategies that have been widely used in industry. Also, simple simulation techniques required for practical controller designs and research on process identification and autotuning are also included. Part Three provides useful process identification methods actually used in industry. It includes several important identification algorithms to obtain frequency models or continuous-time/discrete-time transfer function models from the measured process input and output data sets. Part Four introduces various relay feedback methods to activate the process effectively for process identification and controller autotuning.
