摘要:針對(duì)傳統(tǒng)微波透射法測(cè)量石油含水率存在的測(cè)量誤差大等問(wèn)題，提出了一種基于神經(jīng)網(wǎng)絡(luò)的動(dòng)態(tài)補(bǔ)償方法，確定衰減和相移兩個(gè)參量作為動(dòng)態(tài)補(bǔ)償模型的輸人;針對(duì)傳統(tǒng)BP算法具有收斂速度慢、容易陷人局部極小值等缺點(diǎn)，采用微粒群訓(xùn)練算法對(duì)神經(jīng)網(wǎng)絡(luò)動(dòng)態(tài)補(bǔ)償模型進(jìn)行訓(xùn)練，可使微波透射石油含水率測(cè)量結(jié)果的補(bǔ)償過(guò)程具有尋優(yōu)全局性和精確性。實(shí)驗(yàn)結(jié)果表明，利用該技術(shù)對(duì)石油含水率測(cè)量結(jié)果進(jìn)行校正是一種有效的方法，具有一定的應(yīng)用價(jià)值。

This wil enable the compensation process optimal and accurate overal. Experiments show that the use of the technology in calibrating the measurement result of moisture in petroleum is efective and has certain applicable value.
