A study of oscillation for signal stabilization of nonlinear system
Proceedings of the 10th Wseas International Conference on Automation Information, 2009
The phenomena of desynchronization, synchronization, and forced oscillation has been investigation using describing function theory for a two input and two output nonlinear system containing saturation-type nonlinearities and subjected to high-frequency deterministic signal for the purpose of limit cycle quenching. The analytical results have been compared with the results of digital simulation/Matlab-Simulink for a typical example varying the nonlinear element.
Spectral analysis of nonlinear systems
Theoretical and Applied Mechanics, 2010
Two separate nonlinear differential systems are investigated in the frequency and time domains using plots generated by Mathematica. Spectral density plots are of particular interest as they can conveniently demonstrate the effect on a system of changing one of the parameters. The effects of the starting displacement on the nonlinear pendulum, and the behavior of the Lorenz system when the Rayleigh number is varied, are considered in this way.
Linearized models of a class of nonlinear dynamic systems
Applied Mathematical Modelling, 1989
This paper studies the effect of certain types of nonlinearities on linearized model representations obtainedfrom broadband (Gaussian white noise) input and output experimental data. These linearized models are commonly based on apparent transfer function measurements obtained from the inputoutput cross spectrum and the input spectrum. Since this apparent transfer function measurement is an estimate of the first-order Wiener kernel of the system in the frequency domain, the Volterra-Wiener functional expansions of the considered class of nonlinear differential systems is studied. Explicit analytical expressions are derived that show the dependence of the apparent transfer function on the input power level and the system nonlinearities. An example is presented that demonstrates the character of this dependence.

A mechanism to demodulate a two-tone highfrequency oscillation in nonlinear electronic devices due to an external electromagnetic field is investigated. The results of a demodulation are low-frequency disturbances to the internal circuits of electronic devices. A method for the synthesis of nonlinear compensators on the basis of the operational equations of electronic devices is offered for protection against low-frequency noise. The nonlinear operator of the compensator is designed so that a cascade connection of the electronic device and the compensator is described by the linear Volterra functional. As an example, the compensation of nonlinear transformations of a detector at high-frequency oscillation is synthesized with the use of results of measurements. The accuracy of the executed compensation is estimated.
A method of nonlinear analysis in the frequency domain
Biophysical Journal, 1980
A method is developed for the analysis of nonlinear biological systems based on an input temporal signal that consists of a sum of a large number of sinusoids. Nonlinear properties of the system are manifest by responses at harmonics and intermodulation. frequencies of the input frequencies. The frequency kernels derived from these nonlinear responses are similar to the Fourier transforms of the Wiener kernels. Guidelines for the choice of useful input frequency sets, and examples satisfying these guidelines, are given. A practical algorithm for varying the relative phases of the input sinusoids to separate high-order interactions is presented. The utility of this technique is demonstrated with data obtained from a cat retinal ganglion cell of the Y type. For a high spatial frequency grating, the entire response is contained in the even-order nonlinear components. Even at low contrast, fourthorder components are detectable. This suggests the presence of an essential nonlinearity in the functional pathway of the Y cell, with its singularity at zero contrast.
