Abstract: | This paper presents the hybrid model identification for a class of nonlinear circuits and systems via a combination of the
block-pulse function transform with the Volterra series. After discussing the method to establish the hybrid model and introducing
the hybrid model identification, a set of relative formulas are derived for calculating the hybrid model and computing the
Volterra series solution of nonlinear dynamic circuits and systems. In order to significantly reduce the computation cost
for fault location, the paper presents a new fault diagnosis method based on multiple preset models that can be realized online.
An example of identification simulation and fault diagnosis are given. Results show that the method has high accuracy and
efficiency for fault location of nonlinear dynamic circuits and systems.
