Prediction based Control of Lime Kiln Process in a Paper Mill

 Abstract— Model predictive control (MPC) strategy is an indispensable tool for designing controllers for a multivariable complex, delayed and constrained industrial process. Control system analysis for control of front end temperature and back end temperature in limekiln process has been attempted in the present work using this strategy. The complex dynamics and constraints make this process, an ideal choice for the application of MPC strategy. Linearized model available in literature is selected for design of MPC based controller and the effect of variation of prediction horizon and control horizon, which are important MPC controller tuning parameters, is explored.
