Feedback control of dynamic systems
Addison-Wesley, 1994 - Technology & Engineering - 778 pages
The third edition of this bestselling textbook on undergraduate controls continues to develop students insight into control problems and methods for solving them. Because of the importance of design problems and their motivational effect on students, the authors emphasize design in addition to analysis techniques throughout the text. The book demonstrates the unifying principles behind numerous individual design techniques to assist students in creating their own problem-solving toolbox. The latest edition of Feedback Control of Dynamic Systems reflects many of the recent advances in control system design including balanced coverage of frequency response and state space topics and an introduction to digital control.
