Abstract: Anode baking temperature system is an MIMO control system which has cross-coupling,time-delay and nonlinearity.In order to control baking the temperature accurately,the second order plus time delay control model of the anode baking temperature is identified based on the data gathered from the anode baking furnace scene,which is used for the initial predictive models.A new predictive function decoupling control algorithm for the MIMO systems is proposed.It has been applied to the multivariable predictive functional decoupling control for the anode baking temperature.The simulation and practice control results show that the proposed control system controls precision and robust properties better than the traditional PID control system and is efficient and effective.

Key words: anode baking temperature, modeling, multivariable decoupling control, predictive function control

摘要: 阳极焙烧温度系统是一个含有耦合、大时滞、非线性的多变量控制系统。为实现对阳极焙烧温度的精确控制,依据现场采集的大量温度数据,辨识出阳极焙烧炉温度的二阶惯性滞后控制模型。以此模型为初始预测模型,提出阳极焙烧温度的多变量预测函数解耦控制方法,对焙烧温度进行多变量预测函数解耦控制。仿真和应用结果表明,这种控制方法的控制精度和鲁棒性优于原有的PID方法,具有很好的控制效果。
