一种纤维生产线水浴牵伸过程的智能协同解耦控制

An intelligent cooperative decoupling controller for water bath stretching slot in filament production

提出了一种智能协同解耦控制器,用于纤维生产线中的水浴牵伸槽的液位-浓度复合控制。该控制器由一个控制中枢、多个控制解耦单元及相应的输出单元组成。控制中枢统一协调各控制解耦单元,多个控制解耦单元独立作用并互相交换信息进行对象解耦,控制信号经输出单元综合后作用于控制对象。仿真结果表明,该智能协同解耦控制器能够快速响应控制量的变化,实现耦合控制量的完全解耦和无超调平滑调节,对于纤维生产的牵伸过程较传统控制方法具有更好的控制性能。

An intelligent cooperative decoupling controller（ICDC）is presented and applied to the liquid-level-concentration control in the water bath stretching slot of the filament production.It consists of a control center,several control and decoupling units and their corresponding output units.The control center coordinates each control and decoupling unit which takes effect independently.The system information is exchanged among them to make decoupling.The control signals are integrated by the output unit and then sent to the plant.Simulation results demonstrate that the proposed ICDC can rapidly response to the variation of control variables,completely eliminate the coupling influence and make smooth regulation without overshoot,which has better performance than that of the conventional schemes.
