Numerical ILTs Applied to Weakly Nonlinear Systems Described by Second-Order Volterra Series

Popis výsledku v původním jazyce

In the paper the techniques of numerical inverse Laplace transforms (NILTs) are applied to get the time-domain responses of some classes of weakly nonlinear systems. It is enabled by expanding a response of the system into the Volterra series in connection with the multidimensional Laplace transform. For a given system the Volterra kernels transforms are found, and response Laplace transforms inverted numerically. This procedure does not require an association of variables technique which simplifies thesolution and saves CPU time. In the paper the method is demonstrated on the example of a simple nonlinear electrical circuit. The one- and two-dimensional NILTs based on FFT/IFFT and quotient-difference (q-d) algorithms are modified for this purpose.
