【摘要】 为保证复杂系统的可靠运行,提高故障快速诊断能力,利用解析小波和积分小波分别计算BOX维数和关联维数的方法,融合小波变换模极大值和分维构成一种综合特征提取技术,应用表明,算法能有效提高诊断的准确性和系统的稳定性。
【Abstract】 In order to ensure the reliable running of the complex system, and improve the ability of fast faulty detection, use the analytic wavelet and integral wavelet to calculate the dimensional of BOX and relevant dimension. Also combine the maximum of wavelet transform and detaching dimension to be a pick-up technology. The instance application shows that the efficiency of algorithm has made a big progress.
