    This paper discusses the global output convergence of a class of continuous-time recurrent neural networks (RNNs) with globally Lipschitz continuous and monotone nondecreasing activation functions and locally Lipschitz continuous time-varying thresholds. We establish one sufficient condition to guarantee the global output convergence of this class of neural networks. The present result does not re... View full abstract»

  • Sliding mode control with closed-loop filtering architecture for a class of nonlinear systems

    It is well known by equivalent control theory, that in the sliding mode a low-pass filter, working as an average operator, can capture the desired control fairly well from the switching control signals. However, directly adding the filtered signals in parallel with the switching control does not warrant any improvement in the control system performance. In this work, we make clear the underlying r... View full abstract»

  • Boundedness and stability for nonautonomous bidirectional associative neural networks with delay

    The paper studies the nonautonomous bidirectional associative neural networks systems with time-varying delays. By applying Lyapunov functional method, introducing many parameters, and combining this with the techniques of inequality analysis, a series of criteria of the uniform ultimate boundedness, global exponential stability, and the existence of periodic solutions are obtained. The results ob... View full abstract»

  • On linear-phase FIR filters with variable bandwidth

    Recently, a particular structure for linear-phase finite-impulse response (FIR) filters with a variable bandwidth has received attention. In this structure, the overall transfer function is a weighted linear combination of fixed subfilters, with the weights being directly determined by the bandwidth. An advantage of this structure is that there are only a few adjustable parameters (weights), which... View full abstract»

  • A singular fixed-point homotopy method to locate the closest unstable equilibrium point for transient stability region estimate

    The closest unstable equilibrium point (UEP) method is a well-known direct method of the Lyapunov type for optimally estimating stability regions of nonlinear dynamical systems. One key step involved in the closest UEP methodology is the computation of the closest unstable equilibrium point that has the lowest Lyapunov function value on the stability boundary. In this paper, a new computational al... View full abstract»

  • Synthesis of a pulse-forming reactance network shaping a quasi-rectangular delayed output pulse

    This paper describes the synthesis of a pulse-forming reactance network shaping a delayed quasi-rectangular pulse at the resistive load when the input step voltage is applied. The derivative of the output response is approximated by delayed positive and delayed negative semiperiods of sine-squared function. Then the real and imaginary parts of the approximated Laplace transform of this quasi-recta... View full abstract»

  • An LMI approach to the H filter design for uncertain systems with distributed delays

    Publication Year: 2004, Page(s):195 - 201

    This paper investigates the problem of robust H filter design for linear distributed delay systems with norm-bounded time-varying parameter uncertainties. The distributed delays are assumed to appear in both the state and measurement equations. The problem we address is the design of a filter, such that for all admissible uncertainties, the resulting error system is asymptoticall... View full abstract»

  • The design of high-order bandpass sigma-delta modulators using low-spread single-stage structure

    Publication Year: 2004, Page(s):202 - 208

    A structure for single-stage high-order bandpass sigma-delta modulators (BPSDMs) is presented. The proposed structure introduces an additional internal path in each resonator, thus, adding one degree of freedom in coefficient determination. Coefficient spread can therefore be reduced, resulting in significantly reduced capacitance area in switched-capacitor BPSDM circuits. High-order BPSDMs with d... View full abstract»
