Abstract (en)
[origin: EP3332883A1] A rolled sheet metal mill (910) controller (900) for controlling thickness of sheet metal (922) produced by rolls of the mill (910), the controller (900) comprising one or more processors and code stored on media readable by the one or more processors to control the thickness of the produced sheet metal (922), the controller (900) including an input (940) coupled to receive multiple measured mill parameters including produced sheet metal thickness h that is time delayed from the production of the sheet metal (922), multiple models (935) of the sheet metal mill (910), wherein the sheet metal thickness is modeled as an input varying delay, and at least one internal disturbance model based on one or more of the multiple measured parameters coupled to the input (940), a Kalman filter KF based on the multiple models (935), and an output (955) coupled to control a gap between the rolls that produce the rolled sheet metal (922).
