摘　　要：常规内模控制器具有克服时滞的优点 ,但是当被控对象与模型严重失配情况下 ,常规内模控制器的控制往往难以达到满意的效果。针对具有此种情况的大纯滞后工业过程 ,提出了一种将内模控制与双口控制相结合的改进的内模控制器设计方法。这种结构包含两个独立的控制器 ,适当设计两个控制器可取得比常规内模控制更好的控制效果 [1 ] 。仿真研究表明该控制器在动态性能、静态性能。The normal internal model control can get over the time delay of industrial process, but it cannot achieve a satisfactory performance during great mismatch of internal model with object model. An internal model controller design for industrial process with dominant delay is proposed, it makes internal model control combine with double-port control and is a proved technique. The structure contains two separate controllers. The appropriate design to the two controllers can obtain better performance. The simulation result shows that the controller structure possesses very good control characters such as dynamic and static response performance, robust and disturbance rejection characteristics.
