Online multivariable control of conversion and molecular weight in a continuous solution polymerization reactor

This paper presents a brief overview of some of the results from a comprehensive experimental study (Ogunye, 1994) wherein multivariable and multi-loop stochastic and non-stochastic control policies were applied to a pilot scale methyl methacrylate continuous solution polymerization reactor. The control objectives were the servo-control of conversion and square root of weight-average molecular weight. The multi-loop PID and LQG control strategies applied at the simulation level, proved effective for the servo-control of conversion and square root of weight-average molecular weight using the reactor temperature set-point and initiator flow rate as manipulated variables
