Abstract
Embedded Model Control (EMC) methodology is applied to the web winding control problem. The central task is the design of the Embedded Model (EM), which is the core of the control unit. The winding EM has been constructed in a companion paper. Control algorithms can be shown to act and to be designed as interfaces between EM and the plant command and output channels. Specifically the output-to-EM interface, the measurement law, is just in charge of updating the disturbance dynamics, by disentangling noise and neglected dynamics from the model error. In this respect EMC, while exploiting modern control theories, significantly departs from traditional model-based design as Internal Model Control. EMC application to winding process is detailed and the relevant performance is compared to literature.
