Fuzzy logic control device for continuously operated boiler for cellulose or wood pulp material manufacture

摘要

The control device has an input space (11-13 for a parallel fuzzy regulator, used for regulation of the cooking temperature for the cellulose material, divided in 2 dimensions (e1,e2). The input space can be divided to provide 100% for the outer regulation and 50% and 20% for the inner regulation, with only the inner regulation used when the differences lie within the 20% range and only the outer regulation used when the differences lie outside the 100% range.
