Fuzzy control of rotary cement kiln using sintering zone image recognition

Article analyses modern machine vision-based approaches of the rotary kiln monitoring and control which reduces energy consumption and improve clinker quality. Article describes fuzzy advising control unit developed by the authors. It based on sintering zone state assessment, the kiln rotation period and the relative change of the exhaust gases temperature. Advising control rule base for rotary cement kiln of wet technological process is developed. Structure of fuzzy control system is proposed on the basis of advising control unit. It is applicable both independently and as a part of the existing rotary kiln control systems.

I. Introduction

Development and modernization of automated control systems for rotary kilns is an important task for building materials industry in the production of cement, expanded clay, lime. It allows reduce the energy consumption for burning and improve product quality [1].
