Abstract: By using method of canonical piece-wise linearization and fundamental knowledge of circuit theory,a set of canonical piece-wise-linear equations for nonlinear dynamic networks is presented.This analysis method neednt calculate the time when the response crosses a boundary.The another advantage of this method is that the calculation of dynamic response is converted to algebraic recursive computation.Because the dynamic response can easily be resolved by computer simulation,a basic idea of fault diagnosis method of nonlinear dynamic networks based on wavelet-neural network is also briefly decribed.

Key words: Canonical piece-wise linearization, hybrid parameter equation, state variable, recursive algorithm, wavelet-neural network, fault diagnosis
