摘要
本文利用差压波动信号对水平管气液两相流流型辨识问题进行了研究。以香农熵和阈值熵作为流型辨识的特征量 ,提出了一种基于模糊逻辑的融合辨识新方法。实验结果证明该方法效果良好 。
Flow regime identification in horizontal gas- liquid two- phase flow using differential pressure signal is investigated in this paper. A novel identification method based on fuzzy logic fusion algorithm is presented. Shannon entropy and threshold entropy are extracted as classification features. Experiments show thatthe pro- posed method is successful,and is more effective than identification method only using Shannon or threshold entropy.
