摘　　要：针对化学镀镍主盐离子浓度滞后离线监测和主观经验补加引起表面质量不一致的问题,设计开发了镀液在线分析及自动补加维护系统,研究了硅光电池溶液离子浓度监测方法和基于二次优化控制(TOC)算法的补加控制方案,结果表明:离子浓度监测准确,补加响应迅速、无超调现象。In order to solve the problem of surface quality inconsistency caused by delayed off-line monitoring of metallic main salt in electroless nickel plating and dependent on subjective experience supplement,an on-line analysis and automatic supplement maintenance system for plating solution was designed and developed.The metallic main salt concentration monitoring method of silicon photocell solution and the supplement control scheme based on twice-optimal control(TOC)were studied.The results showed that the monitoring system was accurate,the supplement response was rapid and no overshoot phenomenon.
