    Nonlinear Gain l2 Stability of Nonlinear Feedback Systems with Quantized Measurements
    KAMENEVA, T ; NESIC, D (IEEE - Institute of Electrical and Electronic Engineers, 2008)
    In this paper we address the stabilization problem of the nonlinear feedback systems with quantized measurements in the presence of bounded disturbances. Building on an approach applied in [Liberzon, Neˇsi´c, 2004] to the linear time-invariant systems with quantized feedback, we extend the results of [Kameneva, Neˇsi´c, 2008] to the quantized control systems with nonlinear dynamics. Using the time-sampled scheme proposed in [Liberzon, Neˇsi´c, 2004] and later used in [Kameneva, Neˇsi´c, 2008], we show that the nonlinear gain l2 stability is achievable for the nonlinear systems with quantized feedback.

    On mismatch between initializations at coder/decoder in quantized control
    Kameneva, T ; Nesic, D (Elsevier BV, 2008-12-01)
    This paper analyzes the stability of linear systems with quantized feedback in the presence of a mismatch between the initial conditions at the coder and decoder. We show that using the scheme proposed in Liberzon, Nesic (2007) it is possible to achieve global exponential stability of linear systems with quantized feedback when the coder and decoder are initialized at different initial conditions.

    Input-to-state stabilization of nonlinear systems with quantized feedback
    Kameneva, T ; Nesic, D (IFAC - International Federation of Automatic Control, 2008-12-01)
    This paper addresses the stabilization problem of nonlinear feedback systems with quantized measurements in the presence of bounded disturbances. This paper is an extension of Liberzon, Nesic (2007) to nonlinear systems. Using the scheme proposed in Liberzon, Nesic (2007), we show that input-to-state stability with respect to bounded disturbances is achievable for nonlinear systems with quantized feedback.
