Sliding mode observer for a Takagi Sugeno fuzzy system

Deals with a sliding mode fuzzy observer for nonlinear plants. A nonlinear plant is approximated by a multiple model Takagi Sugeno (TS) fuzzy system and then transformed into a canonical form for which a nonlinear observer is constructed. The paper presents a type of sliding mode fuzzy observer that deals with matched and unmatched uncertainties in the plant model very effectively.
