The essential introduction to the principles and applications of feedback systems—now fully revised and expanded This textbook covers the mathematics needed to model, analyze, and design feedback systems. Now more user-friendly than ever, this revised and expanded edition of Feedback Systems is a one-volume resource for students and researchers in mathematics and engineering. It has applications across a range of disciplines that utilize feedback in physical, biological, information, and economic systems. Karl Åström and Richard Murray use techniques from physics, computer science, and operations research to introduce control-oriented modeling. They begin with state space tools for analysis and design, including stability of solutions, Lyapunov functions, reachability, state feedback observability, and estimators. The matrix exponential plays a central role in the analysis of linear control systems, allowing a concise development of many of the key concepts for this class of models. Åström and Murray then develop and explain tools in the frequency domain, including transfer functions, Nyquist analysis, PID control, frequency domain design, and robustness. Features a new chapter on design principles and tools, illustrating the types of problems that can be solved using feedback Includes a new chapter on fundamental limits and new material on the Routh-Hurwitz criterion and root locus plots Provides exercises at the end of every chapter Comes with an electronic solutions manual An ideal textbook for undergraduate and graduate students Indispensable for researchers seeking a self-contained resource on control theory

Beatrix Potter was a very private person, yet, luckily for us, she was a prolific letter writer. Through her own words to friends, working colleagues and children we can discover the observant, energetic, affectionate and humorous personality she kept hidden from her public. Her life covers a period of immense social change. The restricted existence of a dutiful Victorian daughter, the background against which she first wrote the story of Peter Rabbit, was very different from that of war-time England where she continued to pioneer countryside conservation until her death.

Knots are familiar objects. Yet the mathematical theory of knots quickly leads to deep results in topology and geometry. This work offers an introduction to this theory, starting with our understanding of knots. It presents the applications of knot theory to modern chemistry, biology and physics.

This is a book about young men who learned to play baseball during the 1930s and 1940s, and then went on to play for one of the most exciting major-league ball clubs ever fielded, the team that broke the colour barrier with Jackie Robinson. It is a book by and about a sportswriter who grew up near Ebbets Field, and who had the good fortune in the 1950s to cover the Dodgers for the Herald Tribune. This is a book about what happened to Jackie, Carl Erskine, Pee Wee Reese, and the others when their glory days were behind them. In short, it is a book fathers and sons and about the making of modern America. 'At a point in life when one is through with boyhood, but has not yet discovered how to be a man, it was my fortune to travel with the most marvelously appealing of teams.' Sentimental because it holds such promise, and bittersweet because that promise is past, the first sentence of this masterpiece of sporting literature, first published in the early '70s, sets its tone. The team is the mid-20th-century Brooklyn Dodgers, the team of Robinson and Snyder and Hodges and Reese, a team of great triumph and historical import composed of men whose fragile lives were filled with dignity and pathos. Roger Kahn, who covered that team for the New York Herald Tribune, makes understandable humans of his heroes as he chronicles the dreams and exploits of their young lives, beautifully intertwining them with his own, then recounts how so many of those sweet dreams curdled as the body of these once shining stars grew rusty with age and battered by experience.
