US 2026/0186473 A1 · FEEDBACK CONTROL SYSTEM AND CONTROL METHOD THEREFOR

Abstract

A feedback control system according to one aspect of the present invention comprises: a fabrication unit that fabricates a product by reflecting a predetermined factor value; a test unit that is connected to the fabrication unit to receive the fabricated product and is configured to test the product by applying a test current to the product, and detect a result thereof; and a factor value adjustment unit that is configured to adjust the factor value by using the result detected by the test unit, wherein the result includes information about the time taken for the product to perform a predetermined action when the test current is applied, and wherein the factor value adjustment unit may be configured to compare an average value of the results of a plurality of the products with a predetermined boundary value, and adjust the factor value by using the result.

Dependent claims

A feedback control system comprising:

a manufacturing unit configured to manufacture products by reflecting a preset factor value;
a test unit which is connected to the manufacturing unit to receive the manufactured products, apply a test current to the products to test the products, and detect results thereof;
and
a factor value adjustment unit configured to adjust a factor value using the results detected by the test unit,
wherein the results include information about time for which the test current is applied and the product performs a preset operation, and
the factor value adjustment unit is configured to compare an average value of the results of the plurality of products with a preset boundary value and adjust the factor value using a result thereof.

3 more elements

The feedback control system of claim 1, comprising an average value calculation unit which is electrically connected to the test unit to receive the results and calculates an average value of the results of the plurality of products,

wherein the average value calculation unit includes:
a grouping module configured to classify the plurality of products into a plurality of sets each including a preset number of the products and group the sets into a plurality of groups each including a preset number of the sets;
and
an average value calculation module configured to calculate the average value of the results for each group in which the plurality of products are grouped by the grouping module.

1 more element

A control method of a feedback control system, comprising:

operation (a) of manufacturing, by a manufacturing unit, products according to a preset factor value;
operation (b) of applying, by a test unit, a test current to the manufactured products to test and evaluate the products;
operation (c) of calculating, by an average value calculation unit, an average value of test results of the plurality of products;
operation (d) of adjusting, by a factor value adjustment unit, the factor value using the calculated average value;
and
operation (e) of manufacturing, by the manufacturing unit, the products according to the adjusted factor value.
