Non-linear model based control of a propylene polymerization reactor

摘要: A modified generic model controller is developed and tested through a simulation study. The application involves model-based control of propylene polymerization reactor in which the monomer conversion melt index produced polymer are controlled by manipulating cooling water flow inlet hydrogen concentration. Non-linear designed using simplified non-linear model, order to demonstrate robustness approach for modeling errors. Two parameters updated online ensure that process outputs their predicted values track closely. static inverse with setpoints measured converted some state variables.
