| Abstract:Aiming at the problem of alignment between the measuring data and the dilution water valve actuator in the process of cross directional basis weight of paper-making. CD process modeling and identification were carried out based on the impact test， the response center of the actuator was identified， the response width was calculated， and the mapping table between the actuator and the measuring point was established. Cluster analysis based on physical mapping data identified the contrapuntal model. Through random inspection test， the alignment relationship was verified and offset compensation correction was realized. This method could effectively solve the problem of actuator alignment in the process of cross directional basis weight of paper-making， which improved the adjustment accuracy of CD profile control and thus improves the paper quality. It can provide reference for engineering applications. |
