      Nonlinear estimation for a class of systems 

      Socratous, Y.; Rezaei, F.; Charalambous, Charalambos D. (2009)
      This paper considers nonlinear estimation problems for classes of models, and employs relative entropy to describe the uncertainty classes. Two optimization problems are formulated on general Banach spaces, and their ...

      Time-varying optimal disturbance minimization in presence of plant uncertainty 

      Djouadi, S. M.; Charalambous, Charalambos D. (2009)
      The optimal robust disturbance rejection problem plays an important role in feedback control theory. Here, its time-varying version is solved explicit ly in terms of duality and operator theory. In particular, the optimum ...
