*adaptive fuzzy output feedback control based on any adaptive fuzzy observer*(adaptive fuzzy high-gain observer, adaptive fuzzy sliding mode observer, ...) for a class of single-input-single-output

*SISO uncertain or ill-defined nonaffine nonlinear system*. Indeed, the corrective term of the proposed observer involves a well defined design function which is shown to be satisfied by the commonly used high-gain based observers, namely for the usual high-gain observers and the sliding modes observers together with their implementable versions.

*The design of the underlying update law as well as the robust control term is based on an appropriate filtering of the output tracking error*. This particularly allows to overcome the output observation error filtering or the necessity of the famous strictly positive real (SPR) condition.
