Application of economic MPC to a CSTR process

Abstract

This paper presents an application of Economic Model Predictive Control (EMPC) to a continuously stirred tank reactor (CSTR). As a kind of nonlinear MPC, mechanism models are employed to predict and optimize. The control strategy minimizes the economic objective function under the process constraints composed by mechanism models, bounds, quality and security etc. Several kinds of objective functions for different demands are also analyzed and discussed. The effectiveness of EMPC is illustrated with some numerical simulations.
