摘　　要：考虑草甘膦生产过程中最重要的温度控制问题,给出总体温度监控方案,其中恒温段应用一种带自动修正因子的模糊-PID控制器,应用JX-300进行现场实现,得到较好的应用效果,提高了产品收率。Considering that temperature control is the most important problem in glyphosate process, the temperature monitor and control plan is given. By applying the fuzzy-PID controller with automatic adjustment factor, better temperature trajectory is obtained. The practical application of this controller based on JX-300 DCS is proposed. The result shows that the effect is good.
