Included are the operator-valued versions of tangential Nevanlinna-Pick problem, the Hermite-Fejer problem, the Nehari problem, the Sarason problem, and the two-sided Nudelman problem, adn their nonstationary analogues. The main results concern the existance of solutions, the explicit construction of the central solutions in state space form, the maximum entropy property of the central solutions, and state space parametrizations of all solutions. Direct connections between the various interpolations problems are displayed. Application to the H-infinity control problems are presented. This monograph should appeal to a wide group of mathematicians and engineers. The material is self-contained and may be used for advanced graduate courses and seminars.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ INGRAM","offer_id":52430342127889,"sku":"NLS9783764358891","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"US \/ NEW \/ INGRAM","offer_id":53085209166097,"sku":"NIN9783764358891","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9783764358891.jpg?v=1759169457"},{"product_id":"robust-control-of-infinite-dimensional-systems-book-ciprian-foias-9783540199946","title":"Robust Control of Infinite Dimensional Systems","description":"Since its inception in the early 1980s, H( optimization theory has become the control methodology of choice in robust feedback analysis and design. The purpose of this monograph is to present, in a tutorial fashion, a self contained operator theoretic approach to the H( control for disturbed parameter systems, that is, systems which admit infinite dimensional state spaces. Such systems arise for problems modelled by partial differential equations or which have time delays. Besides elucidating the mathematics of H( control, extensive treatment is given to its physical and engineering underpinnings. The techniques given in the book are carefully illustrated by two benchmark problems: an unstable system with a time delay which comes from the control of the X-29, and the control of a Euler-Bernoulli flexible beam with Kelvin-Voigt damping.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ INGRAM","offer_id":52660657619217,"sku":"NLS9783540199946","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9783540199946.jpg?v=1762265702"}],"url":"https:\/\/www.worldofbooks.com\/collections\/author-books-by-ciprian-foias.oembed","provider":"World of Books ","version":"1.0","type":"link"}
