摘　　要：针对电解铜生产过程电解液成分在线实时测量存在的问题,根据铜电解过程的电化学反应机理和生产过程数据,在改进神经网络隐层节点选择策略和优化训练算法的基础上,提出了电解铜生产过程中电解液成分的软测量方法.仿真分析验证了该方法具有较好的数据拟合和泛化性能。To achieve the online real-time compositional analysis of the electrolyte for the production of electrolytic copper,a soft sensoring technique was proposed for the compositional analysis according to the electrochemical reaction mechanism and production process data of electrolytic copper,based on the improved selection strategy of hidden nodes in neural network and optimized training algorithm. Simulation results showed that the soft sensoring technique proposed is good at data fitting and generalizability. Furthermore,the in-situ running results also showed that the technique can predict accarately the electrolyte composition in time in accordance to the actual change in the electrolytic process.
