Important results from the project
The goals of the project were: 1. An efficient method for decoupling that meets our requirements developed. 2. The decoupling function implemented in ABB´s system. 3. The decoupling function tested and evaluated in ABB´s system. 4. Simple rules and methods for using the function developed. 5. The decoupling function tested in an industrial environment. 6. Article written for scientific journal. All of these points are performed except point 5. The pandemic prevented us. However, everything is completed to perform field tests, and it will be made using laboratory processes instead.
Expected long term effects
We have developed a new efficient method for decoupling of control loops that overcomes the shortcomings that current methods have. The new method is implemented in ABB´s control system and tested in simulation environment with good results. The new method allows for improved product quality and reduced energy consumption in the process industries where it is used.
Approach and implementation
The collaboration between Lund University and ABB has worked very well. The short geographical distance has enabled frequent meetings and close collaboration. Hopefully, this collaboration will continue in future projects.
