| 摘 要： | 针对目前常规两相流流型识别方法在糖厂煮糖罐糖浆识别中精度低的缺点,提出基于电容层析法(ECT)的气液两相流流型判别软测量模型.首先对由ECT传感器采集的检测数据优化处理并提取特征参数作为BP神经网络的辅助变量,气液两相流相应实际流型作为BP网络的主导变量,通过神经网络结构参数的优化训练,构建出二级并行的自组织竞争神经网...

| Abstract: | Aiming at the low accuracy of general flow pattern recognition for boiling sugar syrup in the sugar processing industry,a vapor-liquid two-phase flow pattern identification soft measuring model based on electrical capacitance tomography is proposed.Firstly,detected data of ECT sensor were optimized and then the imputing characteristic parameters were extracted and used as the auxiliary variable of BP neural network,and the corresponding flow pattern worked as the BP network main parameters.Then two parallel... |
