Two step, PID and model predictive control applied on fed batch process

Abstract

The paper presents different control methods applied on a chemical exothermic semi batch reactor. Because of a strongly exothermic chemical reaction the in-reactor temperature is rising very fast depending on the reaction component dosing. Thus, the temperature control is necessary. The system control is generally difficult because of its nonlinear behavior. To simulate the real process a mathematical model including reaction kinetics was used. Three control methods were simulated - two step control with penalization, PID control and model predictive control.
