摘要
针对AR模型对非平稳信号预测不能得到理想结果的问题,本文采用一种基于EMD技术的算法,并在此基础上结合AR模型对非平稳信号进行分析预测。经试验验证,得到了可靠、有效的预测结果 ;在实际应用中对设备的维护和规划提供了充分的理论基础。
Because of the AR model to predict non-stationary signal can't obtain ideal results,The paper adopts a technology based on the EMD,and on this basis,combined with the AR model to analyze and predict non-stationary signal prediction.The model and the method are proved to be reliable and effective by experiments;In the practical application of equipment maintenance and planning provides a sufficient theoretical basis.
