Original Abstract

The techniques of numerical inverse Laplace transforms (NILTs) are applied to get the time-domain responses of some classes of nonlinear systems. It is enabled by expanding the system response into a Volterra series formulated in multidimensional Laplace domains. For a given system the Volterra kernel transforms are found, and the response Laplace transforms inverted numerically. By this way the use of an association of variables technique is avoided to save CPU time. The NILTs based on FFT/IFFT and q-d algorithms are modified for this purpose.
