      Analysis of fluctuation-induced firing in the presence of inhibition 

      Christodoulou, Chris C.; Clarkson, Trevor G.; Bugmann, Guido; Taylor, John G. (IEEE, 2000)
      This paper examines the computational role of inhibition as it moves towards balancing concurrent excitation using the biologically-inspired Temporal Noisy-Leaky Integrator (TNLI) neuron model. The TNLI incorporates ...

      A convex programming approach to the multiobjective H2/H∞ problem 

      Djouadi, S. M.; Charalambous, Charalambos D.; Repperger, D. W. (2002)
      In this paper, Banach space duality theory for the multiobjective H2/H∞ problem developed recently by the authors, is used to develop algorithms to solve this problem by approximately reducing the dual and predual ...

      Frequency domain and dynamic game methods for actuator/sensor selection in systems with sector nonlinearities 

      Demetriou, M. A.; Charalambous, Charalambos D. (2001)
      The purpose of this note is to provide a method for placing actuators and sensors in systems with nonlinear dynamics wherein the choices for actuator and sensor locations are such that the resulting system is rendered ...

      Modeling of traffic flow of automated vehicles 

      Li, K.; Ioannou, Petros A. (2004)
      With the development of near term automatic vehicles following concepts such as intelligent cruise control (ICC) and cooperative driving, vehicles will be able to automatically follow each other in the longitudinal direction. ...

      Multiobjective H2/H∞ by banach space operator theory 

      Djouadi, S. M.; Charalambous, Charalambos D.; Repperger, D. W. (2001)
      In this paper Banach space duality theory and operator theory are combined to show that the optimal performance index in the multiobjective H2/H∞ is equal to the operator induced norm of a particular operator. This operator ...

      A new class of nonlinear robust adaptive controllers 

      Zhang, Y.; Ioannou, Petros A. (1996)
      Recently, a new class of adaptive control schemes, motivated from nonlinear systems theory, has been proposed for minimum phase linear time invariant plants. Under certain assumptions on the plant transfer function, these ...

      On multiobjective H2/H∞ optimal control 

      Djouadi, S. M.; Charalambous, Charalambos D.; Repperger, D. W. (2001)
      In this paper the solutions to the optimal multiobjective H2/H∞ problem are characterized using Banach space duality theory, and shown to satisfy a flatness or allpass condition. Dual and predual spaces are identified, and ...

      Robust capacity of white Gaussian noise channels with uncertainty 

      Charalambous, Charalambos D.; Denic, S. Z.; Djouadi, S. M. (2004)
      This paper concerns the problem of defining, and computing the channel capacity of a continuous time additive white Gaussian noise channel when the true frequency response of the channel is not completely known to the ...

      Robustness of nonlinear control systems with respect to unmodeled dynamics 

      Zhang, Y.; Ioannou, Petros A. (1999)
      In theory, it can be established that nonlinear control laws for linear or nonlinear plants can be used to meet strict performance requirements. The success of these control designs in practical situations will very much ...

      Robustness of nonlinear control systems with respect to unmodeled dynamics 

      Zhang, Youping; Ioannou, Petros A. (1996)
      In this paper, we examine the global stability properties of nonlinear controllers in the presence of high frequency unmodeled dynamics. We develop necessary and sufficient conditions for a general class of nonlinear control ...
