Neuro-fuzzy controller design for lime kiln process

摘要

The lime kiln is a very complex multivariable process with severe non linearities, high degree of coupling and frequent disturbances. In this paper a 2×2 lime kiln process with two manipulated variables namely the fuel gas flowrate, and the percent opening of the induced draft damper and two controlled variables namely front end temperature and back end temperature has been considered.A neuro-fuzzy controller has been designed for it and its setpoint tracking performance has been observed.
