Abstract :
This paper deals of a new metric for multi-model approach, based in phase margin. A quasilinear generalized predictive controller (QGPC) is designed for each chosen operating regime and the metric calculates a weighting factor for each controller. A case study with a simulated debutanizer distillation column is showed.
