Recognising the benefits of improved control, the second edition of Autotuning of PID Controllers provides simple yet effective methods for improving PID controller performance. The practical issues of controller tuning are examined using numerous worked examples and case studies in association with specially written autotuning MATLABr programs to bridge the gap between conventional tuning practice and novel autotuning methods.
The extensively revised second edition covers:
. Derivation of analytical expressions for relay feedback responses.
. Shapes of relay responses and improved closed-loop control and performance assessment.
. Autotuning for handling process nonlinearity in multiple-model-based cases.
. The impact of imperfect actuators on controller performance.
This book is more than just a monograph, it is an independent learning tool applicable to the work of academic control engineers and of their counterparts in industry looking for more effective process control and automation.
This handbook gives comprehensive coverage of all kinds of industrial control systems to help engineers and researchers correctly and efficiently implement their projects. It is an indispensable guide and references for anyone involved in control, automation, computer networks and robotics in industry and academia alike.

Comments on the first edition:
This book is written in a way which not only makes it easy to understand but is also useful to those interested in or working with PID controllers.
The book will be useful to manufacturers and users of control equipment, and also to researchers in the field of automatic tuning.
This book presents a detailed summary of research on automatic layout of device-level analog circuits that was undertaken in the late 1980s and early 1990s at Carnegie Mellon University. We focus on the work behind the creation of the tools called KOAN and ANAGRAM II, which form part of the core of the CMU ACACIA analog CAD system. KOAN is a device placer for custom analog cells; ANANGRAM II a detailed area router for these analog cells. We strive to present the motivations behind the architecture of these tools, including detailed discussion of the subtle technology and circuit concerns that must be addressed in any successful analog or mixed-signal layout tool. Our approach in organizing the chapters of the book has been to present our algo- rithms as a series of responses to these very real and very difficult analog layout problems. Finally, we present numerous examples of results generated by our algorithms. This research was supported in part by the Semiconductor Research Corpora- tion, by the National Science Foundation, by Harris Semiconductor, and by the International Business Machines Corporation Resident Study Program. Finally, just for the record: John Cohn was the designer of the KOAN placer; David Garrod was the designer of the ANAGRAM II router (and its predeces- sor, ANAGRAM I). This book was architected by all four authors, edited by John Cohn and Rob Rutenbar, and produced in finished form by John Cohn.
Who Should Read This Book Looking for some way to make your life better? Something that will give you more control over your future? Do you need a way to overcome some of the mistakes you have made in the past? Are you between thirty-three and sixty-five years old? If so, you need a guide to making your life count. What can you do? Give my six-step program a try. It has made a big difference for me, and can do the same for you. Let this book guide you through the maze of conflicting paths that you encounter in your life. These six steps will give you the confidence you need to face the many challenges life puts in your way. It will give you the necessary time to consider what you want in your future. What Are the Six Steps? Step One is getting control over you body. You start by walking. Then you add small additional changes to your physical activities. Finally, you regularize your exercise while adding new and interesting ways of exercising. Step Two is getting the proper amount of nutrients. This will turn out to be less difficult than it sounds once you are in the exercise mode. You will avoid much of the four harmful food groups - fat, fried, fast, and frozen - along with caffeine, sugar, and sodium. Quickly, you will start noticing how much better you feel. Step Three is improving your brain's performance. This will come from learning challenging new material. This will be good for your brain's capacity, and interesting as well. Step Four is learning to make the best of the challenges at work. Your work represents your opportunity to direct your life toward accomplishments and satisfaction. You need to establish goals to strive for. Volunteer work also is important in this area. Step Five is the problem of financial responsibility. It will require some delay in economic gratification, as you position yourself to handle your health costs and pension. Step Six is the last step, and includes control over distractions such as television that today have almost no upside. In controlling distractions, we create time for the activities that make our lives worthwhile. This gives us time to meet our expectations and to find the joy that surrounds us.
