Embodiment Construction

[0037] according to figure 1 , the influencing device 1 for the rolling stock 2 is controlled by the control device 3 . The influencing device 1 is passed through by the rolling stock 2 . The influencing device 1 influences the rolling stock 2 when the rolling stock 2 passes through the influencing device 1 .

[0038] For example, press figure 2 The influencing device 1 can be configured as a rolling mill train. In this case, the influencing device 1 has at least one rolling stand 4 in which the rolling stock 2 is rolled. In most cases, according to figure 2 There are a plurality of rolling stands 4 in which the rolling stock 2 is rolled sequentially.

[0039] As an alternative, press the image 3The influencing device 1 can be configured as a cooling section for the rolling stock 2 . In this case, the rolling stock 2 is cooled in the cooling section. In most cases, the amount of coolant 6 (for example water) that is applied to the rolling stock 2 is regulated quanti...

Abstract

The method involves adapting a partial model by a control device using deviation of captured measurement variables from model parameters, which are derived using a time curve of property of a rolled product. The partial model and another partial model are adapted by optimizing a cost function, where a penalty term, which depends on the adaptation of the latter partial model, is included in the cost function. The deviation of the measurement variables from the model parameters is included in the cost function. Independent claims are also included for the following: (1) a control program comprising a set of instructions for performing a method for controlling an influencing device that influences a rolled product (2) a control device for an influencing device.

Description

technical field [0001] The invention relates to a control method for an influencing device for a rolled piece, [0002] - wherein the control device controls the influencing device with the control commands in such a way that the influencing device influences the rolling stock according to said control commands, [0003] - wherein the control device detects in real time at least one measured variable dependent on the value of the first property of the rolled stock at the moment of detection of the measured variable in conjunction with the influence exerted on the rolling stock by the influencing device , [0004] - wherein the control device ascertains the model parameters corresponding to the detected measured variables by means of a model of the rolling stock that describes the process in the influencing device, [0005] - wherein the model comprises a first sub-model based on mathematical-physical equations, with which the value of the first characteristic of the rolling ...
