This paper is concerned with an abstract formulation of stochastic uncertain control systems, in which the pay-off is described by the relative entropy between the nominal measure and the uncertain measure, while the uncertain measures satisfy certain energy inequality constraints. The control seeks to maximize the minimum of the relative entropy impacted by the uncertain measure. This formulation leads to connections between minimax games arising in robust control of uncertain systems and Large Deviations theory through the so-called rate functional. In particular, certain monotonicity properties of the optimal solution are discussed, while relations to the well-known Cramer's theorem of large deviations are introduced.

Structural controllability and observability of linear systems over finite fields with applications to multi-agent systems Sundaram, S.; Hadjicostis, Christoforos N. (2013)We develop a graph-theoretic characterization of controllability and observability of linear systems over finite fields. Specifically, we show that a linear system will be structurally controllable and observable over a ...
Decentralized fault accommodation of a class of interconnected nonlinear systems using an adaptive approximation approach Panagi, P.; Polycarpou, Marios M. (2009)This paper presents a decentralized adaptive approximation design for the fault tolerant control of interconnected subsystems. We consider faults that occur in the subsystems local dynamics as well as in the interconnection ...

U. (2017)Decentralized optimization of distributed stochastic dynamical systems with two or more controls of the decision makers (DMs) has been an active area of research for over half a century. Although, such decentralized ...
