Design of Feedback Control Systems is designed for electrical and mechanical engineering students in advanced undergraduate control systems courses. Now in its fourth edition, this tutorial-style textbook has been completely updated to include the use of modern analytical software, especially MATLAB�. It thoroughly discusses classical control theory and state variable control theory, as well as advanced and digital control topics. Each topic is preceded by analytical considerations that provide a well-organized parallel treatment of analysis and design. Design is presented in separate chapters devoted to root locus, frequency domain, and state space viewpoints. Treating the use of computers as a means rather than as an end, this student-friendly book contains new "Computer-Aided Learning" sections that demonstrate how MATLAB� can be used to verify all figures and tables in the text. Clear and accessible, Design of Feedback Control Systems, Fourth Edition, makes complicated methodology comprehensible to a wide spectrum of students. Features � Keyed to today's dominant design tool, MATLAB� � Includes drill problems for gauging knowledge and skills after each topic � Provides state-of-the-art design examples � Uses marginal summaries to guide the reader � Introduces new ideas in the context of previous material, with a guide to the information that follows � Presents practical examples of the latest advances in control sciences.
