| Abstract: | In semi-batch
polymerization reactors, due to changing monomer concentration, the reaction
rate varies non-linearly with the time. The heat transfer characteristics
change by the large changes in the viscosity of the polymer solution over the
reaction and by the environmental conditions like temperature. These factors
complicate the automatic control of polymerization processes. In this study,
considering operational constraints, optimum reactor temperature for the
desired conversion and molecular weight in minimum time was tried to track
using self-tuning PID controller. Tuning parameters of controller were obtained
by using Genetic Algorithm. The fitness function for GA was chosen to be the
integral of the absolute value of the error (IAE). The results show that STPID
controller with genetic algorithm controls the temperature of the semi-batch
polymerization reactor very well. |
