Development of an optimal control scheme for the process of epoxy resins modification with a complicated mathematical model in the control loop.
The problem of optimal control for a highly exothermal technological process with distributed
state variables and with a large dead time is discussed. The main steps of creating a flexible
control system with using the object model in the control loop are considered. It is shown that
heat flux calorimetry is an effective experimental technique for the development of a process
model based upon corresponding multistage kinetic model. It can be also applied to multiphase
reaction systems together with simplified hydrodynamic models for mass transfer phenomena
description. A successful application of this approach for developing the process mathematical
model and its further introduction to the corresponding control system has been demonstrated
for an important industrial process ? modification of epoxy resins with butanediol-1,4 for
further synthesis of epoxy-urethane polymers with improved physico-chemical and mechanical
properties. The process mathematical model makes it possible to specify the optimal operating
mode for each resin and implement the optimal control.
