Title Of Article :
A hybrid model predictive control strategy for nonlinear plant-wide control
Latin Abstract :
A plant-wide control strategy based on integrating linear model predictive control (LMPC) and nonlinear model predictive
control (NMPC) is proposed. The hybrid method is applicable to plants that can be decomposed into approximately linear sub-
systems and highly nonlinear subsystems that interact via mass and energy ¯ows. LMPC is applied to the linear subsystems and
NMPC is applied to the nonlinear subsystems. A simple controller coordination strategy that counteracts interaction eects is
proposed for the case of one linear subsystem and one nonlinear subsystem. A reactor/separator process with recycle is used to
compare the hybrid method to conventional LMPC and NMPC techniques.
