基于模糊CMAC神经网络的4-CBA软测量
4-CBA 传感器 模糊神经网络系统 产品质量
2009/3/9
Soft sensor is attractive in dealing with online product quality measurement by virtue of other easily measured variables. In AMOCO PTA (purified tereph thalic acid) production process, the unavailabi...
A strategy for water and wastewater minimization is developed for continuous water utilization systems involving fixed flowrate (non-mass-transfer-based) operations, based on the fictitious operatio...
The first part of the series of this article proposed a systematic method for the synthesis of continuous water-using system involving both non-mass-transfer-based and mass-transfer- based operations...
