摘　　要：针对酒泉钢铁(集团)有限责任公司碳钢冷轧混合煤气加压站工艺方案不合理、测控方案不完善,无法适应流量负荷变化超过3∶1时煤气热值和压力控制的问题,通过对原有工艺及测控方案的优化改造,采用负荷前馈-反馈控制和煤气热值模糊-比值控制等整体控制方案,实现了大负荷变比混合煤气加压过程的可靠和稳定控制。Aiming at the problems of gas mixing and pressuring station in carbon steel cold rolling plant of JISCO such as unreasonable process, imperfect measurement scheme, and unable to adapt to the gas caloric value and pressure control when load change is more than 3： 1, the authors realize the reliable and stable control on large load change of original process and control scheme, using the load of mixed gas calorific value, etc. gas mixing and pressuring station by optimizing the feedforward-feedback control and fuzzy-ratio control
