APPLICATION OF FUZZY LOGIC IN LIME KILN CONTROL

摘要

This paper shows some examples of fuzzy modelling and control of an industrial lime kiln. The first example concerns with the use of linguistic equations in replacing and developing the control rules of fuzzy controller for the lime kiln flue gas fan. Rule-based deduction is replaced by matrix operations by using integers instead of linguistic levels. The original rule base consists of 22 rules that have been formulated originally based on operator interviews and later tuned manually by trial and error. The second example describes the modelling of burning end of the kiln that was found necessary for designing the fuzzy controller for the burning temperature. The final example shows how the Linguistic Equation Controller controls the burning temperature of the lime kiln.
