This study compares the performance of two widely used control strategies for industrial systems with constraints, namely MPC and selector-based PID control. The simulation studies are carried out using models built from historical data provided to us for an industrial heat exchanger employed at a South-East Asian processing facility. The comparative studies specifically address the deterioration of performance for the two aforementioned strategies in the presence of varying degrees of valve stiction. Aspects of performance recovery via addition of derivative action and retuning of PI parameters for selector-based control are also discussed. The studies suggest that in addition to being a more formal and robust method to handle constraints, MPC is also able to retain its performance to a larger degree in the presence of stiction as compared to selector-based control. © 2022 Elsevier B.V.
