Research on Measuring Moisture in Petroleum Based on Dynamic Compensation Metho
摘要:针对传统微波透射法测量石油含水率存在的测量误差大等问题，提出了一种基于神经网络的动态补偿方法，确定衰减和相移两个参量作为动态补偿模型的输人;针对传统BP算法具有收敛速度慢、容易陷人局部极小值等缺点，采用微粒群训练算法对神经网络动态补偿模型进行训练，可使微波透射石油含水率测量结果的补偿过程具有寻优全局性和精确性。实验结果表明，利用该技术对石油含水率测量结果进行校正是一种有效的方法，具有一定的应用价值。
关键词:石油含水率神经网络微粒群优化算法动态补偿测量精度
