Control System Design with Dead Time Compensation for a Multivariable Lime Kiln Process
Lime kiln is used in numerous process industries such as, papermill, sugarmill, cementmill etc.The lime kilnis 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.
