A digital computer was installed on the Centre Technique du Papier’s experimental machine in order to study the problems involved in the automation of a papermachine.
After a short description of the installation, this paper summarises the work done during the installation phase, in particular, control of the basis weight was designed to go into service as soon as the computer was installed. It uses a control algorithm compensating for the dead time from the point of view of loop stability. The initial results are encouraging.
The same principles will be extended to the control of the dryer section after development of an appropriate model.
