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

From the bestselling author of A Ladder to the Sky—“a darkly funny novel that races like a beating heart” (People)—comes a new novel that plays out across all of human history: a story as precise as it is unlimited. This story starts with a family. For now, it is a father and a mother with two sons, one with his father’s violence in his blood, one with his mother’s artistry. One leaves. One stays. They will be joined by others whose deeds will determine their fate. It is a beginning. Their stories will intertwine and evolve over the course of two thousand years. They will meet again and again at different times and in different places. From Palestine at the dawn of the first millennium and journeying across fifty countries to a life among the stars in the third, the world will change around them, but their destinies remain the same. It must play out as foretold. From the award-winning author of The Heart’s Invisible Furies comes A Traveler at the Gates of Wisdom, an epic tale of humanity. The story of all of us, stretching across two millennia. Imaginative, unique, heartbreaking, this is John Boyne at his most creative and compelling.

Machinations of the Space Princess is a Science-Fantasy role-playing game. That means it's very much about style over substance, mixing science-fiction, magic and psionics in a game world that owes much more to Metal Hurlant and Star Wars than it does to 2001 or Bova's Grand Tour. This is a game of strangeness and fun, of space pirates and beautiful alien princesses, of living planets and robot hordes, of blasters at noon. This is... Sexy, sleazy, swords and sci-fi! A full game combining old and new school thinking, packed with GM and player advice and with simple tools for creating your own monsters, adversaries, weapons, armour, ships and alien races.
