A sequential linearized model based predictive controller is designed using the DMC algorithm to control the temperature of a batch MMA polymerization process. Using the mechanistic model of the polymerization, a parametric transfer function is derived to relate the reactor temperature to the power of the heaters. Then, a multiple model predictive control approach is taken in to track a desired temperature trajectory. The coefficients of the multiple transfer functions are calculated along the selected temperature trajectory by sequential linearization and the model is validated experimentally. The controller performance is studied on a small scale batch reactor.

To produce a certain polymer with desired properties, some of polymerization variables should be controlled. In this paper, a oil bath was designed and constructed for the heating and cooling of the reactor. Then, a mechanistic model was developed for the solution polymerization of methyl methacrylate in a batch reactor. This model is highly non-linear. A Globally Linearizing Control (GLC) strategy was applied to control the reactor temperature. A linear PI controller was designed to eliminate the error. The controller performance was viable and the previously developed GLC method is suitable for the oil heating system. Copyright  2002 IFAC

The kinetics model was therefore compared with experimental results obtained under non-isothermal conditions.…”

The radical addition co-polymerisation of 2-hydroxyethylmethacrylate and butylacrylate is carried out in a continuously operating Buss-Kneader. To calculate temperature profiles over the length of the kneader the heal balance is solved. For the heat transfer coefficient a model based on the penetration theory, is used. This model is experimentally verified. The reaction kinetics of the radical addition polymerisation are studied in a differential scanning calorimeter. The polymerisation kinetics are modeled using non-stationary radical concentrations. The calculated temperature profiles over the length of the Buss-Kneader are a good approximation of the experimental data.
