Abstract:

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.
