Control System Design with Dead Time Compensation for a Multivariable Lime Kiln Process
Keywords:
Lime Kiln, Dead Time, Multivariable, Smith Predictor, Set-Point TrackingAbstract
Lime kiln is used in numerous process industries such as, paper mill, sugar mill, cement mill etc. The limekiln is
fundamentally challenging to operate proficiently due to intricate structure with non-linear reaction kinetics, and
large dead time. It turns out to be dangerous if it is functioned outside the set points. So, the automation of this
process is very critical for optimization of product quality, product rate and economy. The current research work
deals with a 2x2 lime kiln model. Having done its multivariable analysis, its decoupling has been done. Using
MATLAB, dead time compensation is done with smith predictor design and its performance is compared to that
of control system without dead time compensation
