Modelling and Predictive Control of Milk Pasteurisation in a Plate Heat Exchanger

This paper investigates the possible usage of Model Predictive Control (MPC) in a pasteurisation plant outlining the resulting benefits over classical control method, for instance Proportional Integral Derivative (PID) control. However MPC requires a plant model, a physical first principals model of the pasteuriser is developed and validated using data gathered on site at the "Glanbia" milk production unit in Drogheda, Ireland. A PFC controller is then designed using this model, simulated results are presented and compared with the results given by the PID controller in operation
