This paper presents the application of an identification algorithm based on local model networks able to split the full model dynamics in linear parameter-varying (LPV) models for different regions on the process operating range. It is shown that a model based controller equipped with an efficient LPV model performs better than when a single linear time-invariant (LTI) model is used. Results demonstrated that model adaptation over several regions provides better system representation leading to more efficient and consistent control in already implemented control loops.
