Time domain characteristics of rational systems with scale-invariant frequency response

IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 1996

The class of rational systems characterized by a magnitude response which is scale invariant for a specific scale change, or equivalently γ-homogeneous rational systems, are useful in modeling power-law processes. Such systems can be constructed by cascading frequency-scaled replicas of a prototype rational function which satisfies certain conditions. In this communication, we study the time domain characteristics of such systems. ...


Bifurcations in two-dimensional piecewise smooth maps-theory and applications in switching circuits

IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 2000

Recent investigations on the bifurcation behavior of power electronic DC-DC converters have revealed that most of the observed bifurcations do not belong to generic classes such as saddle-node, period doubling, or Hopf bifurcations. Since these systems yield piecewise smooth maps under stroboscopic sampling, a new class of bifurcations occur in such systems when a fixed point crosses the border between ...


Error estimation of recurrent neural network models trained on a finite set of initial values

IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 1997

This letter addresses the problem of estimating training error bounds of state and output trajectories for a class of recurrent neural networks as models of nonlinear dynamic systems. The bounds are obtained provided that the models have been trained on N trajectories with N independent random initial values which are uniformly distributed over [a,b]/sup m/ /spl isin/ R/sup m/.

  • Time domain characteristics of rational systems with scale-invariant frequency response

    The class of rational systems characterized by a magnitude response which is scale invariant for a specific scale change, or equivalently γ-homogeneous rational systems, are useful in modeling power-law processes. Such systems can be constructed by cascading frequency-scaled replicas of a prototype rational function which satisfies certain conditions. In this communication, we study the time domain characteristics of such systems. We show that, in the case of degree-1 or degree-2 prototypes, the magnitudes of the partial fraction expansion coefficients constitute a geometric sequence. Furthermore, in the degree-2 case, the angles of the partial fraction expansion coefficients are equal. Using these properties, we demonstrate that the impulse response of a e, γ-homogeneous rational system is essentially a linear combination of dilations of a prototype waveform and therefore exhibits a wavelet-like decomposition.

  • Bifurcations in two-dimensional piecewise smooth maps-theory and applications in switching circuits

    Recent investigations on the bifurcation behavior of power electronic DC-DC converters have revealed that most of the observed bifurcations do not belong to generic classes such as saddle-node, period doubling, or Hopf bifurcations. Since these systems yield piecewise smooth maps under stroboscopic sampling, a new class of bifurcations occur in such systems when a fixed point crosses the border between the smooth regions in the state space. In this paper we present a systematic analysis of such bifurcations through a normal form: the piecewise linear approximation in the neighborhood of the border. We show that there can be many qualitatively different types of border collision bifurcations, depending on the parameters of the normal form. We present a partitioning of the parameter space of the normal form showing the regions where different types of bifurcations occur. We then use this theoretical framework to explain the bifurcation behavior of the current programmed boost converter.

  • Design of an nth order Dickson voltage multiplier

    In this brief we propose a simple dynamic model of a Dickson voltage multiplier with N stages, which is obtained starting from the models previously proposed for less than 5 stages. The model allows increased insight into the dynamic behavior of these circuits and provides a valuable tool for determining a first version design.

  • Noise performance of chaotic communication systems

    We present cumulant analysis tools suitable fur the study of chaos communication systems. The approach uses random process models for all signals involved. The analysis is applied to the differential chaos shift keying (DCSK) scheme and its close relative-the transmitted reference (TR) approach under additive white Gaussian noise channel conditions. Approximative as well as exact performance figures are derived, the latter agreeing with results recently presented in the literature. The parameter ranges for the application of either solution are specified. The noise robustness problem present in DCSK/TR is discussed and quantified.

  • Time-domain simulation of power electronics circuits using state variable quadratic extrapolations

    A new stepwise time-domain analysis technique for power electronics circuits is presented. At each simulation step the rate of change of each state variable is determined by the corresponding reactive element parasitic resistance and state value obtained after performing a modified nodal analysis (MNA). A quadratic state trajectory description for each reactive element is formulated. To ensure the correct topological operation of the power stage, the algorithm monitors the position and checks the validity of all switches, requiring no a priori knowledge of their switching relationships. All computations require simple algebraic manipulations of resistive networks only. An example of simulating the response of a zero-voltage-transition PWM buck converter is illustrated. The results are favorably compared to the previous method using constant nodal voltage approximation, experimental measurements, and the commercial software PSpice.

  • Robust nonlinear H/sub /spl infin// synchronization of chaotic Lur'e systems

    We propose a method of robust nonlinear H/sub /spl infin// master-slave synchronization for chaotic Lur'e systems with applications to secure communication. The scheme makes use of vector field modulation and either full static state or linear dynamic output error feedback control. The master-slave systems are assumed to be nonidentical and channel noise is taken into account. Binary valued continuous time message signals are recovered by minimizing the L/sub 2/-gain from the exogenous input to the tracking error for the standard plant representation of the scheme. The exogenous input takes into account the message signal, channel noise and parameter mismatch. Matrix inequality conditions for dissipativity with finite L/sub 2/-gain of the standard plant form are derived based on a quadratic storage function. The controllers are designed by solving a nonlinear optimization problem which takes into account both channel noise and parameter mismatch. The method is illustrated on Chua's circuit.

  • The role of synchronization in digital communications using chaos. I . Fundamentals of digital communications

    In a digital communications system, data is transmitted from one location to another by mapping bit sequences to symbols, and symbols to sample functions of analog waveforms. The analog waveform passes through a bandlimited (possibly time-varying) analog channel, where the signal is distorted and noise is added. In a conventional system the analog sample functions sent through the channel are weighted sums of one or more sinusoids; in a chaotic communications system, the sample functions are segments of chaotic waveforms. At the receiver, the symbol may be recovered by means of coherent detection, where all possible sample functions are known, or by noncoherent detection, where one or more characteristics of the sample functions are estimated. In a coherent receiver, synchronization is the most commonly used technique for recovering the sample functions from the received waveform. These sample functions are then used as reference signals for a correlator. Synchronization-based receivers have advantages over noncoherent ones in terms of noise performance and bandwidth efficiency. These advantages are lost if synchronization cannot be maintained, for example, under poor propagation conditions. In these circumstances, communication without synchronization may be preferable. The main aim of this paper is to provide a unified approach for the analysis and comparison of conventional and chaotic communications systems. In Part I, the operation of sinusoidal communications techniques is surveyed in order to clarify the role of synchronization and to classify possible demodulation methods for chaotic communications.
