Dynamics of the paper/board production line Dynamic time constants and open-loop stability determine the agility of a system. The papermaking process has large time constants and it is inherently stable. Thus, the process keeps its operating point with little control effort, but once a disturbance has entered the system, its effects last long. Changes from
