Some contributions to estimation for model-free control

This paper describes some contributions to Model Free Control (MFC). For example, its properties about disturbance rejection are analyzed. It is also shown that it is possible to propose new estimation methods for an extended version for MFC using time-varying parameters of an ultra-local model. In particular it is emphasized that these parameters can be estimated using alternative and standard adaptation methods. An application to a thermal process model illustrates one specific point of the new adaptive approach.
