Orthogonal Embedding of Time-Varying Systems,ulation and solution of problems relating to stabilization and robustness of linear time-varying systems. Here we consider a problem that has its origins in classical network theory. A network is characterized as a stable linear systems as defined in Section 5.5..is passive if.≥ 0, and lossless if.=消毒 发表于 2025-3-27 01:21:18
Orthogonal Embedding of Time-Varying Systems,ins in classical network theory. A network is characterized as a stable linear systems as defined in Section 5.5..is passive if.≥ 0, and lossless if.= 0. In operator theoretic terminology, passive systems are contractions, ‖S‖ ≤ 1, and lossless systems are isometries.instructive 发表于 2025-3-27 06:35:03

A Distance Formula and Some Consequences,In this chapter we present a formula for the distance of a given operator from an algebra of operators of a certain type. This formula plays a major role in the theory to be developed here. We attain, as consequences of this formula, the Nehari and Arveson distance formulae.控制 发表于 2025-3-28 03:21:49
Factorization Theorems,In Chapter 3, we considered two situations of algebras of operators containing particular subalgebras whose matrix representations are lower triangular:Inline Equation性别 发表于 2025-3-28 07:15:28

Uniform Optimal Control,In this chapter we study a class of optimal control problems. To provide motivation we begin with a simple sensitivity minimization problem for a feedback system where .and C are multiplication operators.
