Japan, 1981 CONTROL OF A CEMENT KILN BY FUZZY LOGIC TECHNIQUES L. P. Holmblad and J-J. Ostergaard F. L. (I Co. A/S, Vigerslev Alle 77, DK-2500 Valby, Denmark Abstract. By applying the methodology of fuzzy logic the operat10nal experience of manual control can be used as the basis for implementing automatic control schemes.
Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.

process makes it inadmissible for automatic control. The objective of the kiln control system is to ensure the production of desired quality clinker efficiently and to supply it to the cement mill uninterruptedly as per the demand. In this paper, a Fuzzy Logic Controller system is proposed
This paper develops an Internet-based fuzzy control system for an industrial process plant to ensure the remote and fuzzy control in cement factories in Algeria. The remote process consists of control, diagnosing alarms occurs, maintaining and synchronizing different regulation loops. Fuzzy control of the kiln ensures that the system be operational...
A special language, Fuzzy Control Language, facilitating computer programming with the relevant control algorithms is outlined. Based on experience gained through fuzzy control on actual operation of cement kilns, it is concluded that fuzzy control is a practicable and effective way of increasing the level of coordinative control on multi ...

The remote process consists of control, diag-nosing alarms occurs, maintaining and synchronizing different regulation loops. Fuzzy control of the kiln
The first industrial fuzzy application was in a cement kiln in Denmark in 1982. The first VLSI fuzzy electronics was by Masaki Togai and Hiroyuki Watanabe in 1984. In 1987, Yamakawa built the first analog fuzzy controller. The first digital fuzzy processors came in 1988 by Togai (Russo, pp. 2-6).
A fuzzy control system is a control system based on fuzzy logic—a mathematical system that analyzes analog input values in terms of logical variables that take on continuous values between 0 and 1, in contrast to classical or digital logic, which operates on discrete values …
A supervisory fuzzy control of back-end temperature of rotary cement kilns Abstract: Rotary Kiln is the central and the most complex components of cement production process. The first point at the beginning of the process, which is called back-end, is the calcining zone of the kiln and has a significant role on the quality of the clinker.
Adaptive Fuzzy Logic Controller for Rotary Kiln Control. The Rotary Kiln forms the heart of the cement manufacturing plant where most of the energy is being consumed by the burning of clinker, which when powdered and mixed with gypsum gives cement. In order to assure acceptable qualities for the clinker, it is important to make sure that the ...
