Linear control system analysis and design 4th ed.

This textbook is intended to provide a clear, understandable, and motivated account of the subject which spans both conventional and modern control theory. The authors have tried to exert meticulous care with explanations, diagrams, calculations, tables, and symbols. They have tried to ensure that the student is made aware that rigor is necessary for advanced control work. Also stressed is the importance of clearly understanding the concepts which provide the rigorous foundations of modern control theory. The text provides a strong, comprehensive, and illuminating account of those elements of conventional control theory which have relevance in the design and analysis of control systems. The presentation of a variety of different techniques contributes to the development of the student's working understanding of what A.T. Fuller has called "the enigmatic control system." To provide a coherent development of the subject, an attempt is made to eschew formal proofs and lemmas with an organization that draws the perceptive student steadily and surely onto the demanding theory of multi-variable control systems. It is the opinion of the authors that a student who has reached this point is fully equipped to undertake with confidence the challenges presented by more advanced control theories as typified by chapters 18 through 22. The importance and necessity of making extensive use of computers is emphasized by references to comprehensive computer-aided-design (CAD) programs. - Preface.
