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

This monograph proposes a minimalist, phase-based approach to the derivation of coordinate structures, utilizing the operations Copy and Match to account for both the symmetries and asymmetries of coordination. Data are drawn primarily from English, German and Dutch. The basic assumptions are that all coordinate structures are symmetric to some degree (in contrast to parasitic gap and many verb phrase ellipsis constructions), and these symmetries, especially with ellipsis, allow syntactic derivations to utilize Copy and Match in interface with active memory for economizing with gaps and assuring clarity of interpretation. With derivations operating at the feature level, troublesome properties of coordinate structures such as cross-categorial and non-constituent coordination, violations of the Coordinate Structure Constraint, as well as coordinate ellipsis (Gapping, RNR, Left-Edge Ellipsis) are accounted for without separate mechanisms or conditions applicable only to coordinate structures. The proposal provides support for central assumptions about the structure of West Germanic.

The scope and scale of Operation Barbarossa—the German invasion of the Soviet Union—make it one of the pivotal events of the Second World War. Yet our understanding of both the military campaign as well as the “war of annihilation” conducted throughout the occupied territories depends overwhelmingly on “top-down” studies. The three million German soldiers who crossed the Soviet border and experienced this war are seldom the focus and are often entirely ignored. Who were these men and how did they see these events? Luther and Stahel, two of the leading experts on Operation Barbarossa, have reconstructed the 1941 campaign entirely through the letters (as well as a few diaries) of more than 200 German soldiers across all areas of the Eastern Front. It is an original perspective on the campaign, one of constant combat, desperate fear, bitter loss, and endless exertions. One learns the importance of comradeship and military training, but also reads the frightening racial and ideological justifications for the war and its violence, which at times lead to unrelenting cruelty and even mass murder. Soldiers of Barbarossa is a unique and sobering account of 1941, which includes hundreds of endnotes by Luther and Stahel providing critical context, corrections, and commentary.
