A practical application of recent results in model and controller validation to a ferrosilicon production process

This paper presents the application of our recently developed theory on model validation for control and controller validation in a prediction error framework to a realistic industrial case study. The industrial application concerns the control of the silicon concentration in a ferrosilicon production process. Our case study produces findings about the design of the validation experiment (validation in open or closed loop). It also illustrates the respective merits of the tools developed, respectively, for control oriented model validation and for the validation of a particular controller
