Abstract
A web meandering correction system () includes: an edge detector () that detects an edge position signal of a web; an HPF processing unit () that executes a high-pass filtering process on the edge position signal using a predetermined lower limit frequency as a reference; a high-frequency noise analyzing unit () that analyzes high-frequency noise that has passed through the HPF processing unit (); an LPF processing unit () that executes a low-pass filtering process on the edge position signal using a predetermined upper limit frequency as a reference; a coefficient setting unit () that sets a coefficient that determines the characteristics of the low-pass filtering process on the basis of a result of analysis by the high-frequency noise analyzing unit (); and a meandering correction unit () that corrects meandering of the web on the basis of information acquired by the LPF processing unit ().
