【Abstract】 In this paper, the general framework of the soft-sensing technology based on neural networks is proposed and the soft-sensing of the naphtha endpoint is studied by means of a multilayer feedforward and the generalized chemotaxis algorithmfor the practical fluidized catalytic cracking unit. The theoretical analysis and simulation show that the practical characteristic of objects can be described very well by the model.更多还原
