"Daniel Liberzon is associate professor of electrical and computer engineering at the University of Illinois, Urbana-Champaign. He is the author of ""Switching in Systems and Control""."
This is an extremely well-crafted textbook. If you plan to teach a first course to advanced students on the calculus of variations and optimal control and you like the selection of topics that the author has chosen to present (and I do), it is the text you need. What impresses me most is the careful balance between the formal derivations and the explanations that precede or accompany the statements and proofs. . . All in all, it is a first-rate, enjoyable text. --Zvi Artstein, Mathematical Reviews Clippings Each chapter ends with a rich and useful section of notes and references. The exercises are merely problems or even theorems. The author of the book presents a large list of references and a detailed index of notions, names, and symbols. The graphical presentation of the book is pleasant. . . . [T]his book is well written, it fully deserves all its goals mentioned at the beginning of the review, and is a pleasure to read it. --Marian Muresan, Mathematica
