LEARNING DEVICE, LEARNING METHOD AND PROGRAM THEREFOR

Document Type and Number:

WIPO Patent Application WO/2019/176772

Kind Code:

A1

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 the basis 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 obtained by 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.
