摘　　要：阳极焙烧烟气负压是一个多变量耦合的控制对象,为实现其精确控制,依据现场实际测得的负压数据,辨识出烟气负压的控制模型,以此模型为初始预测模型,提出了一种多变量预测函数解耦控制算法,对焙烧9个烟道烟气负压进行多变量预测函数解耦控制仿真和实际应用,并与原有PID控制进行了试验比较,表明这种控制方法的控制精度和鲁棒性优于原有的PID控制方法,具有很好的控制效果。Anode baking flue gas negative pressure is a cross-coupling multivariable control system. To realize the control accurately, the control models of flue gas negative pressure are identified based on the date gathered from the anode baking furnace scene. Then the model is used for the initial predictive models, a new predictive function decoup- ling control algorithm for the multivariable systems is proposed. The multivariable predictive function decoupling con- trol for the baking nine flue gas negative pressure is simulated and applied in practice. The results of simulation and practical control show that the control precision and robust properties of proposed control system is better than that of traditional PID control system, therefore the proposed control system has good control effect.
