      Characterization of the Optimal Disturbance Attenuation for Nonlinear Stochastic Uncertain Systems 

      Charalambous, Charalambos D.; Rezaei, F.; Djouadi, S. M. (2003)
      This paper is concerned with an abstract formulation of stochastic optimal control systems, in which uncertainty is described by a relative entropy constraint between the nominal measure and the uncertain measure, while ...

      Stochastic uncertain systems subject to relative entropy constraints: Induced norms and monotonicity properties of minimax games 

      Charalambous, Charalambos D.; Rezaei, F. (2007)
      Entropy and relative entropy are fundamental concepts on which information theory is founded on, and in general, telecommunication systems design. On the other hand, dissipation inequalities, minimax strategies, and induced ...
