The multi-rollers high speed web transport system here analyzed is composed by four sections driven each by a controlled servomotor. The main problem for the controller design deals with the validation of a mathematical system model. Some experimental tests were carried out giving reference values to the 4 motors and saving the system outputs. Unknown parameters were estimated to describe the experimental data with a well-tuned model. In this operation it was very important to include digital filters for the experimental data. These results will be used for improving the control performances.
