PID Controllers: Theory, Design, and Tuning

Rating:
Summary: Good Reference
Review: Most industrial controllers are PI or PID controllers, and few textbooks or accademic Journal articles address them. I've been working in industrial process control for over twenty years and this book is one of the best one's I've found on PI/PID control. The presentation is practical rather than theoretical (some might miss not having more math). The first four chapters summarize when PI/PID control is useful and present several of the traditional tuning methods. Chapter 5 presents new tuning algorithms that are easy to apply in practice and usually result in better control that older methods (like the atrocious Ziegler-Nichols). Chapter 6 gets side-tracked discussing commercial products that will rapidly be out of date. Chapter 7 returns to practical applications and simple examples - I was amused to see boiler drum level control discussed in one page when we've spent so much time on this problem! The one thing missing from the book is control of nonlinear systems - even the simple example of level control with a fixed stroke-time valve is omitted - but aside from this shortcoming, it is a most useful book.

Rating:
Summary: It is a good reference for engineering students.
Review: This book is quite good reference for engineering students to do their design project about control system.
