Problems solved by technology
[0006] When the control rules do not conform to reality due to changes in operating conditions, etc., it is difficult to output a certain degree of control accuracy because the control rules are fixed.
In addition, once the shape control is in motion, the operator does not perform manual operation (interfering with the control), so it is difficult to find a new control rule through the manual intervention of the operator.
Furthermore, when rolling a new standard rolling material, it is difficult to set a control rule corresponding to the material.
[0007] As described above, in conventional shape control, control is performed using preset control rules, so there is a problem that it is difficult to correct the control rules.

PROBLEM TO BE SOLVED: To learn an optimum operation method for actual data without deteriorating a state of a plant to be controlled.SOLUTION: A plant control device that performs control by recognizing a combination pattern of actual data of a plant to be controlled with respect to the plant to be controlled, comprises: a control method learning device for learning a combination of the actual data of the plant to be controlled and a control operation; and a control execution device that performs control of the plant. The control execution device includes a control rule execution unit, a control output determination unit, and a control output suppression unit. The control method learning device includes a control result pass / fail determination unit, a learning data creation unit, and a control rule learning unit. Since the control method learning device performs the learning, a combination of separate actual result data and control operation is obtained for a plurality of control targets according to the state of the plant to be controlled, and the combination of the obtained actual data and the control operation is used as a predetermined combination of the actual data of the plant to be controlled and the control operation in the control rule execution unit.SELECTED DRAWING: Figure 1
Description
technical field [0001] The present invention relates to a whole set of equipment control device and its control method, a rolling mill control device and its control method, and a storage medium storing programs in real-time feedback control using artificial intelligence technologies such as neural networks. Background technique [0002] Conventionally, plant control based on various control theories has been carried out in order to obtain desired control results in various plants. [0003] As an example of a plant, for example, in rolling mill control, as an example of control, fuzzy control and neuro-fuzzy control are applied as a control theory for shape control that controls the undulation state of a plate. Fuzzy control was applied to shape control using coolant, and neuro-fuzzy control was applied to shape control of Sendzimir rolling mill. Among them, as shown in Patent Document 1, the similarity ratio between the difference between the actual shape pattern detected ...
