This book offers a thorough analysis of the principles of classical and modern feedback control. Organizing topic coverage into three sections--linear analog control systems, linear digital control systems, and nonlinear analog control systems--helps the reader understand the difference between mathematical models and the physical systems that the models represent. FEATURES/BENEFITS NEW--SIMULINK simulation program--Illustrates feedback effects. Helps demonstrate design examples and problems. NEW--MATLAB's symbolic mathis employed to verify transforms and to solve differential equations directly. NEW--Computer verification of results. Exposes users to a short MATLAB program when working almost all examples and problems. NEW--Design procedures implemented in MATLAB m-files. NEW--Improved practical application examples. Allows the reader to better relate the mathematical developments to physical systems. Chapter-end problems. Most chapter-end problems lead the reader through a second method of the solution, so that they can verify results. Transfer-function and state-variable models. Familiarizes users with both models for the analysis and design of linear analog systems. System stability discussion--Along with the Routh-Hurwitz stability criterion. Coverage of nonlinear system analysis methods. Emphasizes describing-function analysis, linearization, and the state-plane analysis. Early coverage of expanded frequency-response design criteria. Helps explain closed-loop systems. Digital Control Systems. Provides the reader with the basic principles of digital control. Time-scaling differential equations section. Maximum text/course flexibility --Places more advanced material toward the end of each chapter. Topics can be easily omitted, enabling instructors to tailor the book to meet their needs.Phillips, Charles L. is the author of 'Feedback Control Systems', published 1999 under ISBN 9780139490903 and ISBN 0139490906.
