Summary

Organized into three principal areas (analog control systems, digital control systems, and nonlinear analog control systems), Feedback Control Systems has been significantly revised to provide more practical examples, more thorough design coverage, and increased emphasis on computer-aided analysis and design using MATLAB. Specifically, the Third Edition features: clearer, more detailed explanations of basic material; a new section (4.5) dealing with time-scaling differential equations designed to help readers better relate the transfer functions of the systems of the examples to those of practical systems; additional practical applications in the form of examples and end-of-chapter problems that better relate mathematical developments to physical systems; and completely new end-of-chapter problems, many using MATLAB programming for solution verification. In addition, this edition retains the emphasis on practical systems, develops transfer-function and state-variable analog models, reviews matrices, develops an analytical design procedure that applies both root-locus design and Bode design, and presents a table of Laplace transforms and z-transforms in the appendices.
