Control and Filtering for Discrete Linear Repetitive Processes with H infty and ell 2--ell infty Performance
No full textRepetitive processes are characterized by a series of sweeps, termed passes, through a set of dynamics defined over a finite duration known as the pass length. On each pass an output, termed the pass profile, is produced which acts as a forcing function on, and hence contributes to, the dynamics of the next pass profile. This can lead to oscillations which increase in amplitude in the pass to pass direction and cannot be controlled by standard control laws. Here we give new results on the design of physically based control laws for the sub-class of so-called discrete linear repetitive processes which arise in applications areas such as iterative learning control. The main contribution is to show how control law design can be undertaken within the framework of a general robust filtering problem with guaranteed levels of performance. In particular, we develop algorithms for the design of an H? and dynamic output feedback controller and filter which guarantees that the resulting controlled (filtering error) process, respectively, is stable along the pass and has prescribed disturbance attenuation performance as measured by and – norms
Wu Sangui (Usanqueius) – dowódca i buntownik na kartach Historiae Sinarum Imperii Tomasza Szpota Dunina
Full text linkIn his work on Chinese history, Tomasz Ignatius Szpot Dunin SJ did not miss the attitudes of significant Chinese commanders during the historical watershed period of the fall of the Ming dynasty and its replacement by the Manchurian Qing dynasty. One of them was Wu Sangui, who initially supported the Ming against external and internal enemies, only to contribute to the success of the Manchurian invasion at a crucial moment and, after almost three decades of operating under the new dynasty’s sovereignty, to declare obedience to it and lead the so-called Three Feudatories Rebellion. The affair was well-known in Europe and even became the subject of literary interest in the 18th century. Szpot Dunin does not succumb to extreme tendencies in his description, skilfully considers the circumstances of the decision and presents a nuanced yet incisive picture of Wu Sangui’s character, intentions and failures.Tomasz Ignacy Szpot Dunin SJ w swoim dziele poświęconym historii Chin nie ominął postaw znaczących chińskich dowódców w okresie przełomu historycznego, jakim był upadek dynastii Ming i jej zastąpienie przez mandżurską dynastię Qing. Jednym z nich był Wu Sangui, który początkowo wspierał Mingów w walce z zewnętrznymi i wewnętrznymi wrogami, by w kluczowym momencie przyczynić się do powodzenia najazdu mandżurskiego, a po niemal trzech dekadach działania pod zwierzchnością nowej dynastii wypowiedzieć jej posłuszeństwo i stanąć na czele tzw. Rebelii Trzech Lenników. Sprawa ta była znana w Europie i stała się nawet przedmiotem zainteresowania literackiego w XVIII w. Szpot Dunin nie poddaje się w swoim opisie skrajnym tendencjom, umiejętnie rozważa okoliczności decyzji i przedstawia zniuansowany, ale jednocześnie wyrazisty obraz postaci Wu Sangui, jego zamiarów i niepowodzeń

Assessing the George W. Bush Presidency: A Tale of Two Terms
Full text linkIn one of the first volumes assessing the full two terms of the George W. Bush presidency, Wroe and Herbert have gathered the work of leading American and European scholars. In fifteen succinct and incisive chapters, authorities such as Jim Pfiffner, John Maltese, Graham Wilson and Alan Gitelson offer assessments of the Bush administration's successes and failures. Extensive attention is paid to Bush's foreign policy, including 'The War on Terror' but the focus is broadened to absorb not only the Bush Doctrine and its repercussions, but also his trade and homeland security policies. The president's domestic leadership in economics and social policy is investigated, as are his dealings as president with the other institutions of the U.S. political system. The result is a comprehensive guide to the Bush presidency and its legacy
