Conveyor Belt Control System Summary

A

In this example application, a Fuzzy Logic Unit is used to control two conveyor
belts for product packaging. The products are carried on conveyor A at random
intervals, but at a fixed speed. The boxes are carried at regular intervals on con-
veyor B, which runs parallel to conveyor A at a speed controlled by the Fuzzy
Logic Unit.
The Fuzzy Logic Unit adjusts the speed of conveyor B so that the boxes arrive at
the same time as the products. The required information is the offset between
the product and the box and the rate that the offset is changing. A conventional
control system eliminates the offset between the product and the box, but some-
times no speed adjustment is necessary even though there is a large offset, so
the system controlled by the Fuzzy Logic Unit is much more efficient.
