      The capacity of unstable dynamical systems-interaction of control and information transmission 

      Charalambous, Charalambos D.; Kourtellaris, C. K.; Loyka, S.; Tzortzis, I. (Institute of Electrical and Electronics Engineers Inc., 2017)
      Feedback capacity is extended beyond classical communication channels, to stochastic dynamical systems, which may correspond to unstable control systems or unstable communication channels, subject to average cost constraints ...

      Distributed frequency control of inertia-less AC microgrids 

      Cady, S. T.; Hadjicostis, Christoforos N.; Domínguez-Garcia, A. D. (Institute of Electrical and Electronics Engineers Inc., 2015)
      In this paper, we introduce a generation control architecture for microgrids that ensures stable and synchronized operation at a specific frequency. We also propose a distributed implementation of this architecture that ...

      Encoder, controller and decoder design of jump linear systems over jump communication channels 

      Ma, X.; Djouadi, S.; Charalambous, Charalambos D.; Denic, S. (2013)
      In this work, we focus on the encoder, decoder, and controller design for jump linear systems over jump communication channels.The plant state information (PSI) and the channel state information (CSI) are assumed to be ...

      Lie algebraic methods in optimal control of stochastic systems with exponential-of-integral sample cost: Examples 

      Charalambous, Charalambos D. (1998)
      The optimal control of partially observed stochastic systems with exponential-of-integral-sample cost is considered. The concept of sufficient statistic algebra is introduced to construct finite-dimensional controllers. ...

      Modal analysis reduction of multi-body systems with generic damping 

      Louca, Loucas S. (Caltek s.r.l., 2012)
      Modal analysis of multi-body systems is broadly used to study the behavior and controller design of dynamic systems. In both cases, model reduction that does not degrade accuracy is necessary for the efficient use of these ...

      Robust control of uncertain context-sensitive probabilistic Boolean networks 

      Denic, S. Z.; Vasic, B.; Charalambous, Charalambos D.; Palanivelu, R. (2009)
      Uncertainty is an intrinsic phenomenon in control of gene regulatory networks (GRNs). The presence of uncertainty is related to impreciseness of GRN models due to: (1) Errors caused by imperfection of measurement devices ...

      Signalling of information in networked stochastic dynamical control systems 

      Charalambous, Charalambos D.; Kourtellaris, C.; Tzortzis, I. (Institute of Electrical and Electronics Engineers Inc., 2018)
      Signalling of information is made feasible from one controller to another controller, in a networked control system consisting of two interconnected control systems. In this application, controller 2 of control system 2 ...
