多变量约束过程的预估协调控制

COORDINATED CONTROLLER FOR MULTIVARIABLE CONSTRAINTSPROCESS

分析了多变量受约过程的状况，指出变量受约时，正常系统与“胖”、“瘦”系统间将互相转换，讨论了这种复杂系统基于模型预估控制的最优控制策略，这种策略已成功地应用于催化裂化装置反应深度控制。

For the multivariable constraints process,a normal svstem will transfer to“thin or“fat” system if some manipulated variables were limited or some controlled variableswere inside the desired zone. For this complex system,the coordinated controller based onpredictive control strategy was introduced.
