Sulla base di documenti, interviste e trasmissioni televisive da Washington, Londra, Parigi, Bonn, Berlino, Varsavia, Mosca e una dozzina di altri luoghi, il 1989 descrive come la Germania si unì, iniziò l'espansione della NATO e la Russia rimase alla periferia del nuovo Europa. Questa edizione aggiornata contiene una nuova postfazione con le prove più recenti sulle origini del 1990 dell'espansione della NATO dopo la Guerra Fredda.Princeton studies in international history and politics, 147EuropaStoriaSec. 20.BNCF940.558SAROTTE,Mary Elise476020cbaITcbaREICAT996400850203316EBER1989242735UNISA03401nam 2200445 450 991082260580332120230802001534.03-8325-9700-X(CKB)4340000000242411(MiAaPQ)EBC5216740(Au-PeEL)EBL5216740(CaPaEBR)ebr11539389(OCoLC)102180448058a1c68a-9c48-4d86-8022-3edeb0dd2d03(EXLCZ)99434000000024241120180522d2012 uy 0engurcnu||||||||txtrdacontentcrdamediacrrdacarrierOptimal control of switched systems with application to networked embedded control systems /Daniel GörgesBerlin :Logos Verlag,[2012]©20121 online resource (206 pages)Forschungsberichte aus dem Lehrstuhl für RegelungssystemePublicationDate: 201203103-8325-3096-7 Long description: This thesis addresses optimal control of discrete-time switched linear systems with application to networked embedded control systems (NECSs). Part I focuses on optimal control and scheduling of discrete-time switched linear systems. The objective is to simultaneously design a control law and a switching (scheduling) law such that a cost function is minimized. This optimization problem exhibits exponential complexity. Taming the complexity is a major challenge. Two novel methods are presented to approach this optimization problem: Receding-horizon control and scheduling relies on the receding horizon principle. The optimization problem is solved based on relaxed dynamic programming, allowing to reduce complexity by relaxing optimality within predefined bounds. The solution can be expressed as a piecewise linear (PWL) state feedback control law. Stability is addressed via an a priori stability condition based on a terminal weighting matrix and several a posteriori stability criteria based on constructing piecewise quadratic Lyapunov functions and on utilizing the cost function as a candidate Lyapunov function. Moreover, a region-reachability criterion is derived. Periodic control and scheduling relies on periodic control theory. Both offline and online scheduling are studied. The optimization problem is solved based on periodic control and exhaustive search. The online scheduling solution can again be expressed as a PWL state feedback control law. Stability is guaranteed inherently. Several methods are proposed to reduce the online complexity based on relaxation and heuristics. Part II focuses on optimal control and scheduling of NECSs. The NECS is modeled as a block-diagonal discrete-time switched linear system. Various control and scheduling codesign strategies are derived based on the methods from Part I regarding the structural properties of NECSs. The methods presented in Part I and II are finally evaluated in a case study.Networks on a chipReliabilityNetworks on a chipReliability.621.381531Görges Daniel1656845MiAaPQMiAaPQMiAaPQBOOK9910822605803321Optimal control of switched systems with application to networked embedded control systems4009932UNINA
