Combining the time-frequency location and multiple-scale analysis of wavelet transform with the nonlinear mapping and self-learning of neural networks, an error decomposition method in dynamic measuring system is proposed. According to whole-system dynamic accuracy theory, the whole-error model of dynamic measuring system is given, and then the whole-error is decomposed into sub-errors by wavelet neural networks, which are traced so that units of the system are found which generate these errors and error transmission characteristic is controlled.
