发酵过程酵母浓度的软测量
Soft Sensor Technique Applied to Yeast Concentration in the Commercial Fermentation
【摘要】 针对发酵过程酵母浓度的测量,提出一种基于支持向量机的软测量建模方法。仿真证明,该方法比典型的RBF神经网络软测量有着明显的优势,对于实现发酵过程自动控制和优化运行有着重大的意义。
【Abstract】 This article presents a soft sensor modeling via support vector machine considering the problem of yeast concentration in the commercial fermentation.Experiments show that the SVM-based soft sensor has the evident advantage than the RBF-based soft sensor.The SVM-based soft sensor is of important significance for the automatic control and optimal running in the commercial fermentation.
