| Abstract |
Optimizing the control of multi-motor drives in processing machines with continuous moving webs, normally the influence of the web forces is neglected. Poor dynamic behaviour is observed in the case of unfavourable dimensions of a plant. By solving a Riccati matrix equation a decentral reduced-order state observer is found which reconstructs the web forces. An adaptation to practical demands yields a simplified first-order observer circuit which is able to decouple a drive from the web forces. Its parameters are independent from the speed of the plant. The circuit is robust against large variations of the parameters of the system. Theoretical and experimental investigation has shown that the dynamic performance of a cascade controlled large-scale system can be improved considerably. |
