摘　　要：针对氧化铝生产过程中赤泥洗涤水温控制问题和赤泥洗涤过程工艺的特点,为了增加洗涤效率、降低溶液粘度及减少铝酸钠溶液水解,采用灰色预测模糊控制方法,建立了一种基于灰色模型的预测模糊温度控制的赤泥洗涤水温控制系统。首先建立水温灰色预测模型,然后利用模糊推理求得电动调节阀输出的精确值。实际应用结果表明,该方法较常规的模糊控制具有较高的控制精度、良好的动态特性和鲁棒性,达到了良好的控制效果。According to the water temperature control problem in the alumina processing industry and characteristic of washing process,to increase washing efficiency and reduce solution conglutination and hydrolyzation of sodium aluminate,a predictive fuzzy temperature control system based on grey model adopting grey predictive fuzzy control method is designed to stabilize water temperature during the washing.Firstly,predictive model is established then,precision value is concluded using fuzzy inference.Practical appl...
