| Popis: |
This work aims to develop a control system capable to maintain the viscosity curve measured in-line during the continuous production of a non-Newtonian fluid inside a range of values of viscosity which represent the target. Rheological models capable of relating the viscosity curve of the final product to the input variables were introduced to mimic changes in the production of a non-Newtonian fabric. A one-point control has been developed that acts modifying the mass flows of ingredients injected in the production plant to reject disturbances or track set-point changes. The developed controller is capable to maintain the viscosity curve inside the desired confidence range of viscosities. The methodology is easy to implement in similar continuous production processes by adjusting the model for other ingredients. |
