| Abstract: | An intelligent control system used in polyacrylonitrile （PAN） precursor production is introduced. This system can detect concentration by on-line apparatus, adjust the feed water to solution automatically so as to maintain concentration stability. It has great significance to improve the control of process parameters, and has broad application prospects in acrylic fibers production in wet-spinning and PAN precursor production for carbon fiber. |
