  • Patent number: 6745169
    Abstract: A learning process for a neural network for open-loop or closed-loop control of an industrial process with time-variable parameters. The neural network is configured either as an open-loop or closed-loop-control network with which the process is controlled. The neural network is trained with the current process data so that it builds a model of the current process. The neural network can also be configured as a background network which is trained during operation with representative process data so that it builds an averaged model of the process over a longer period of time. After a certain learning time or upon the occurrence of an external event, the open-loop or closed-control network is replaced by the background network.

  • Patent number: 6697699
    Abstract: Method for influencing relevant quality parameters of a rolling strip, particularly the profile or flatness of the rolling strip, in a roll stand with rolls, by adjusting the crownings of the rolls, i.e., the surface geometry of the rolls in the longitudinal direction of the rolls, wherein the crowning of the rolls is adjusted by an adjustable cooling of the rolls or of their surfaces in longitudinal direction of the rolls. The cooling of the rolls is adjusted by a controller (1) as a function of the actual value (pactual) of the crowning and a predetermined setpoint value (psetpoint) of the crowning.

  • Patent number: 6679626
    Abstract: A method for determining the thermal material properties of metal shaped parts from a model is disclosed, which describes the thermal material properties of the metal shaped part. At least one thermodynamic parameter (p) is formed as a linear combination consisting of at least one base function (hi) and of at least one weighting factor (gi), whereby the base function (hi) describes the thermal material properties, and the weighting factor (gi) takes the influence of the alloying elements on at least one thermodynamic parameter (p) into account. The method makes it possible to conduct a sufficiently precise determination of the thermal material properties with a smaller time requirement.

  • Publication number: 20030089431
    Abstract: The joint properties of a metal strip being rolled in a hot strip rolling mill, especially a steel strip, are adjusted in the cooling stretch of said mill by cooling. According to the invention, a time-related cooling course is predetermined for each strip point of the metal strip. An individual cooling curve is established as a function of time for each strip point, the established time curve is constantly compared with the model time-related cooling curve for each strip point and process control signals for controlling and/or regulating the cooling stretch are derived from this comparison. The corresponding device is provided with a calculating device and a process control device.

  • Patent number: 6418354
    Abstract: The width of bands to be laminated on a mill train is adjusted by vertical upsetting rollers, resulting, however, in a narrowing at the band ends due to the asymetric material flow there. In order to solve the problem, the upsetting rollers are so designed as to move at the passage of the band ends in keeping with a curve defined according to specified parameters. The parameters are based on neuro-computer made predictions related to the milling process.

  • Patent number: 5988259
    Abstract: Method and apparatus for controlling the cooling of a strand in a continuous casting installation, in which the cooling or, respectively, the solidification behavior of the strand ensures by means of the quantity of cooling agent used for cooling the strand, whereby the required quantity of cooling agent is determined, constantly and in real time, dependent on a predetermined target temperature distribution. A cooling model is used with which a temperature distribution in the strand can be calculated from a quantity of cooling agent.

  • Patent number: 5855131
    Abstract: Process and device for influencing the profile of a rolled strip in a roll stand by affecting the camber of the rolls, i.e., the surface geometry of the rolls in the longitudinal direction of the rolls. The camber of the rolls is affected by influencing the temperature profile of the rolls or their surface in the longitudinal direction of the rolls. In one embodiment, the temperature profile of the surfaces of the rolls is controlled by cooling the surfaces of the rolls.

  • Patent number: 5778151
    Abstract: In the control of a material-processing process in a regulated system, a preliminary adjustment of the system takes place at the beginning of each process cycle as a function of a precalculated process parameter. A material characteristic which is relevant for the process and which in turn is dependent on state variables (such as the composition of the material and its temperature), is included in an advance calculation of the process parameter. The relationship between the state variables and the material property is modelled in a neural network which forms a prediction value for the material property on its output side. As a function of the deviation between the prediction value and an actual value for the material property which is determined based on measuring the process parameter during the process cycle, an adaptive change of the network parameters takes place in the sense of reducing this deviation.

  • Patent number: 5740686
    Abstract: In rolling a metal strip in a roughing line and a finishing line, the rolling process in the roughing line is adjusted as a function of a predicted value for the change in width of the metal strip in the finishing line such that the metal strip has a given specified finished strip width on leaving the finishing line. In order to permit a reliable prediction of the change in width despite the lack of accurate information regarding the dependence of the change in width on influencing parameters that affect the process, this dependence is simulated in a neural network whose network parameters are adapted after each passage of a metal strip through the finishing line as a function of the influencing parameters measured or calculated during the passage and the measured actual change in width.

  • Patent number: 5673368
    Abstract: In known processes for conducting a process in an automatically controlled system, the system is preset at the beginning of each process run based on at least one process parameter. The at least one process parameter is precomputed with a model of the process, containing at least one model parameter and input values supplied to the model. During the process, the input values and the process parameter are measured and used to adaptively improve the precomputed process parameter after the process run. A neural network is used to determine the model parameters whose dependence on the input values is unknown or insufficiently known. Network parameters of the neural network are modified after each process run to adapt the model to the actual process events.

  • Patent number: 5608842
    Abstract: In known methods for conducting a process in an automatically controlled system, the system is preset at the beginning of each process run according to at least one process parameter. The at least one process parameter is precomputed with a model of the process which is supplied with input values. During the process, the input values and the process parameters are measured and are used after the process run to adaptively improve the precomputed value of the process parameters. To simplify and improve the precomputed value of a model having a plurality of partial models, computed results of the partial models are supplied to a neural network. The neural network produces the process parameters to be precomputed as a network response. The network parameters of the neural network are modified after each process run to adapt the precomputed value to the actual process events.
