【 摘 要 】

References(11)Cited-By(2)Based on analysis of wavelet transform, we studied how to extract the frequency band and multi-scale qualitative features of process measurement signals and proved that the extracted features could describe the process operating region stably and completely. Combining the pattern inductive algorithm, a new method of process operating region recognition based on wavelet transform is proposed. The theoretical analysis and real application results have verified that the proposed method is feasible and effective.
