Proportionalintegralderivative (PID) controllers are the most adopted controllers in industrial settings. The availability of microprocessors and software tools and increasing demand for higher product quality at reduced cost have stimulated research to devise new methodologies to improve their performance and ease of use.

"Practical PID Control" focuses on those functionalities that can provide significant improvements in PID performance in combination with parameter tuning. In particular, the choice of filter to make the controller proper, the use of a feedforward action and the selection of an anti-windup strategy are addressed. The choices of identification algorithm and model reduction technique are analysed in the context of model-based PID control. Widely adopted PID-based control architectures (ratio and cascade control) and performance assessment are also covered. Simulation and experimental results are provided better to illustrate the different methodologies and to discuss their pros and cons.

Gives the reader new methods for improving the performance of the most widely applied form of control in industry Demonstrates how the new functionality can be added to a controller without compromising its simplicity of use Offers solutions to practical problems facing the control engineer using PID Includes supplementary material: sn.pub/extras

Autorentext

Antonio Visioli received the Laurea degree in electronic engineering from the University of Parma, Parma, Italy, and the Ph.D. degree in applied mechanics from the University of Brescia, Brescia, Italy, in 1995 and 1999 respectively. His Ph.D. dissertation was on control strategies for industrial robot manipulators. From 1997 to 2005 he has been assistant professor and from 2005 he is associate professor of Automatic Control at the Department of Electronics for Automation, University of Brescia, Italy. His research interests include industrial robot control and trajectory planning, input-output-inversion-based control and process control. In particular, industrial (PID) controllers have always been one of the main subjects of his research, as shown by a large number of publications in refereed journals and conference proceedings. Overall, he is the author or co-author of more than 100 papers in international journals and refereed conference proceedings and he is the author of the book Practical PID Control published by Springer. He cooperates with different companies (e.g. Whirlpool Europe and Yokogawa Italia) and universities. Dr. Visioli is a senior member of IEEE, member of IFAC and member of the national board of Anipla (Italian Association for the Automation). Qing-Chang Zhong joined the Department of Electrical Engineering and Electronics, University of Liverpool as a Senior Lecturer in August 2005. He received his first Ph.D. degree in Control Theory and Engineering from Shanghai Jiao Tong University, China in 1999 and his second Ph.D. degree in Control and Power Engineering from Imperial College London in 2004, winning the Best Doctoral Thesis Prize. He started his career in control engineering in 1990 after receiving his first degree. He joined the School of Electronics, University of Glamorgan as a Senior Lecturer in early 2004 and was promoted to Reader in May 2005. He is a Senior Member of IEEE, a Member of IET andUKACC. He (jointly with his co-authors, when appropriate) has made significant contributions to control theory and time-delay systems and published a monograph, Robust Control of Time-delay Systems, with Springer in 2006. The majority of his research results in control were published in the top two international journals in systems and control: IEEE Transactions on Automatic Control and Automatica. His other research interests cover automotive electronics, power electronics and renewable energy. He is leading an EPSRC-funded Network for New Academics in Control Engineering with more than 60 members, which aims to shape the future of collaborative research in control and related areas. He serves on the Technical Committee 2.2 (Linear Control Systems) of the International Federation of Automatic Control and has been on the Int. Program Committees of several international conferences. He has been invited to visit various institutions all over the world and hosted visitors from different countries. His research is funded by EPSRC and industrial partners.
