Learning device, learning method and program therefor

Abstract

This learning device provides a learned model to an adjuster containing a learned model leaned in such a manner that a controller outputs a predetermined compensation amount to the controller, on thebasis of the specific parameter of an object to be processed, in a control system comprising a controller for outputting a command value obtained by compensating a target value on the basis of a compensation amount and an object to be controlled which is controlled so as to perform predetermined processing on an object to be processed. The learning device comprises: an evaluation unit which acquires operation data that includes the target value, command value and control variable and evaluates the quality of the control variable; a learning unit which generates compensation candidates on the basis of the operation data, and learns, as teacher data, the generated compensation amount candidates and specific parameters for the object to be processed, and generates a learned model; and a setting unit which provides the learned model to the adjuster if the quality evaluated by the evaluation unit is within a permissible range, on the basis of a control variable when a command value obtainedby compensating a target value on the basis of the compensation amount output by the generated learned model is imparted to the object to be controlled.

Description

technical field [0001] The present invention relates to a learning device, a learning method and a program thereof. Background technique [0002] In the case of processing, assembling, etc. of the material using a control device such as a press machine, usually the material that has been processed once cannot be restored to its original shape. Therefore, it is impossible to appropriately adjust the control amount while repeatedly processing the same material. Therefore, it is important to quantify the relationship between the properties of the material and the control input, to provide an appropriate control input when new processing is performed, and to obtain an appropriate control amount. [0003] For example, Patent Document 1 discloses a press system capable of reducing the influence of variations in plate thickness when manufacturing press-worked products. The press system of Patent Document 1 includes a press machine and a supply device for supplying workpieces to t...

Problems solved by technology

[0002] In the case of processing and assembly of materials using a control device such as a press machine, usually the material that has been processed once cannot be restored to its original state.

Therefore, it is impossible to properly adjust the control amount while performing repeated processing on the same material.
