Résumé: | A generalized multiconductor transmission line
(MTL) model is integrated with the polynomial chaos stochastic
Galerkin method (PC-SGM) in order to predict the stochastic
response of a nonuniform multitwisted bundle of twisted-wire pairs
(MTB-TWP) with random parameters, which is excited by random
plane waves. The twist pitches of such nonuniform MTB-TWP are
considered to be spatial stochastic functions, where its parametric
equations are derived in their general form. Moreover, by taking
the geometry deformation of the MTB-TWP cable into account,
some of its parameters are represented by random variables, and
the incident plane-wave fields can also be changed in some ran-
dom ways. After that, the PC-SGM is applied to the stochastic
telegrapher’s equations in order to obtain deterministic ones that
can be solved by using the MTL model. Therefore, the effects of
the uncertainties of the parameters on the common mode and the
differential mode currents are investigated in details, where, in
each case, the probability density function is given. The results are
validated in comparison with Monte Carlo (MC) method, where
a very good agreement is obtained. It is shown that the PC-SGM
simulation time is much smaller than that of the MC method as the
number of random variables is relatively small. |
