Controlling system for cardboard-sheet manufacturing apparatus

摘要

A controlling system (100) for a cardboard-sheet manufacturing apparatus includes an FF/FB controlling unit (101), a PID controller (102), and a knowledge database (103). The FF/FB controlling unit (101) differentiates between compensation for a dynamic characteristic and that for a static characteristic based on the knowledge database (103), and switches between FF control and FB control. The PID controller (102) operates based on a two-degree-of-freedom PID algorithm. The FF/FB controlling unit (101) adjusts a feedback gain based on information stored in the knowledge database (103).
