The aim of this paper is to present robust model predictive control (MPC) with integral action to optimize control performance of heat exchangers selected from a network, in the presence of fouling. The robust MPC represents an advanced optimization-based strategy to handle uncertain systems. The integral action is implemented to remove steady-state errors of controlled variables. The time-varying parameters of the heat exchangers in the presence of fouling are handled in the form of parametric uncertainties. Simulation of the closed-loop control confirms the significantly improved control performance.
