Adaptive control of conversion in a simulated solution polymerization continuous stirred tank reactor

An adaptive controller with improved stability and robustness features that account for unmodeled dynamics and unmeasured disturbances is applied to the control of monomer conversion (i.e. productivity) of a continuous solution methyl methacrylate polymerization reactor in the presence of reactive i...

Summary:An adaptive controller with improved stability and robustness features that account for unmodeled dynamics and unmeasured disturbances is applied to the control of monomer conversion (i.e. productivity) of a continuous solution methyl methacrylate polymerization reactor in the presence of reactive impurities with drifting concentration levels. This control approach is evaluated at the simulation level using the initiator concentration in the feed as the control variable. The performance of the adaptive controller is compared against those of a minimum variance and a self-tuning controller. 55 ref.--AA
