Shape Control Method of Cold Rolled Steel Sheet Using Variable-Observing Least Squares Control Method

摘要

The present invention relates to the shape control of cold-rolled iron using the variable- forgetting least-squares control method. In particular, in the cold-rolled shape control, the shape influence coefficient is estimated using the variable- forgetting least-squares control method. And a shape-control method of a cold rolled steel sheet using a variable- forgetful least square control method for controlling the shape of a cold rolled steel sheet by calculating a shape pattern.;Using the variable-oblivion least squares control method, the shape influence coefficient of cold rolled steel sheet is estimated by the following equation,;The shape of the cold rolled steel sheet is controlled by calculating a shape pattern using the derived shape parameter, controlling a roll by outputting a signal corresponding to the shape pattern to the shape control unit.
