Patent ID: 6915180

Claim:
An identification method for position correspondence in the cross direction, which identifies the position correspondence between the actuators for controlling the cross direction profile and the measuring points for measuring said profile in manufacturing equipment for sheet form products that includes a plurality of actuators for controlling cross direction profiles of sheet form products and a cross direction controller which receives a target profile and a measured profile in the cross direction of said sheet form products as the inputs and sends out a manipulated variable that controls said plurality of actuators, including: a step in which the manipulated variable sent out from said cross direction controller is received and model calculation is carried out using a process model which simulates the process including said plurality of actuators, a step in which the deviation between this model calculation output and said measured profile is received and the optimum values for position correspondence, interference width, and process gain are calculated so that said deviation is minimized, a step in which the resulting optimum values of position correspondence, interference width, and process gain are set to the position correspondence, interference width and process gain in said process model, and a step in which the optimum value of said position correspondence is set to the position correspondence in said cross direction controller; and performing these settings with the same timing as control in said cross direction controller or for a longer period.
