Predictive Functional Control of counter current heat exchangers

Abstract

Abstract A full first principle model of counter current heat exchangers is used as the internal model of a classical PFC controller. With the use of a specific physical “convexity property” of this type of process, a full straightforward first-principle model is used as the internal model of the controller. The whole strategy is implemented in a classical industrial PLC, which controls this nonlinear process with a minimum effort.
