Modern Control SystemsModern control systems is the most widely used textbook for introductory control theory courses taught in a variety of engineering disciplines. The book stays on top of recent developments in the field while providing a thorough treatment of the fundamentals. Five different types of endofchapter problems combined with running design examples throughout the text provide an unparalleled learing experience for students. The eleventh edition is the most current and relevant control theory textbook available and continues the tradition of excellence established in previous editions.New to this editionApproximately 30% of the endofchapter problems are new or revisedAll computeraided design problems have been updated for this editionChapters 2 and 3 have been extensively updated in order to emphasize the importance of modeling in the overall control design process.Chapters 4 and 5 have been rewitten to better integrate key material, differentiate important topics, and elininate subject overlap.At the beginning of each chapter are new "Desired chapter outcomes" sections tot address new Abet specific requirements.Designoriented material has been added in each chapter. In the early chapters, the emphasis is on modeling and in latter chapters on chapterrelevant design methods.Supporting resources are updated and available at www.prenhall.com/dorf.
