对自适应小波（ＡｄａｐｔｉｖｅＷａｖｅｌｅｔｓ）分析理论加以推广，提出了广义自适应小波分析技术理论（ＧｅｎｅｒａｌｉｚｅｄＡｄａｐｔｉｖｅＷａｖｅｌｅｔｓ），并应用基因遗传算法（ＧｅｎｅｔｉｃＡｌｇｏｒｉｔｈｍｓ，简称ＧＡｓ）实现了振动信号的广义自适应小波分析。计算机仿真结果表明ＧＡｓ用于自适应小波和广义自适应小波分析是十分有效的方法。最后，应用广义自适应小波分析对内燃机进行了诊断，证明了该技术的工程实用性和有效性 In this paper, Generalized Adaptive Wavelets (GAWT) theory is proposed to generalize Adaptive Wavelets analysis theory, and the generalized adaptive wavelet analysis of vibration signals is realized by using Genetic Algorithms (GAs). Computer simulation results show that GAs are very effective for adaptive wavelet and generalized adaptive wavelet analysis. Finally, the generalized adaptive wavelet analysis is applied to diagnose the internal combustion engine, which proves the engineering practicability and effectiveness of this technology
