Abstract

This paper develops an approach for optimal selection of signalโ€adapted wavelet in deโ€noising. The new method employs Wu's elimination algorithm to construct compacted orthogonal wavelets. The threshold cost function is used as the objective function during choosing of the wavelet. The approach is validated by its application to deโ€noising for onโ€line partial discharge (PD) measurement. The physical experiments and field tests show that the method improves the suppression of noise for onโ€line PD measurement with stronger robustness. Copyright ยฉ 2004 John Wiley & Sons, Ltd.

In this paper, we present two on-line adaptive control algorithms for non-linear plants using neural networks. The architecture used is based on the concept of specialized learning, which was first proposed by Psaltis et al. and suffers from two main problems, namely lack of knowledge of the plant J
