本论文采用智能控制算法来改进投药控制系统,用PSO 算法改进BP 神经网络,实现最佳投药量控制。并将智能算法用于嵌入式控制系统,将其作为一个加药站点置于工业以太网上的任何位置,可以很方便的对加药进行控制。 关键词:PSO,神经网络,嵌入式系统,加药控制器 Abstract: In the paper, using the intelligent control arithmetic to improve the dosing control system. PSO is used to improve the BP-NN, it can achieve the optimal dosage. The intelligent control arithmetic is applied to the embedded system. This controller will be used as a dosing station to be placed in anyplace of the Ethernet so as to control the dosage very convenient. Key words: PSO, BP-NN, Embedded system, dosing controller
