Design of observer based nonlinear model predictive controller for continuous stirred tank reactor

Abstract

Model Predictive Control MPC schemes are now widely used in newlineprocess industries for the control of key unit operations Linear Model newlinePredictive Control LMPC schemes which make use of linear dynamic model newlinefor prediction limit their applicability to a narrow range of operation or to newlinesystems which exhibit mildly nonlinear dynamics The key unit operation in newlinechemical plants namely the Continuous Stirred Tank Reactor CSTR newlineexhibits a highly nonlinear dynamic behavior The need to achieve tighter newlinecontrol of such strong nonlinear process CSTR has led to a more general newlinecontrol formulation in which nonlinear dynamic model is used for prediction newline newline
