Abstract :
Deals with local fuzzy Thau-Luenberger observers for nonlinear plants. A nonlinear plant is approximated by a Takagi-Sugeno (TS) fuzzy multiple model with affine subsystems for which local linear fuzzy observers are constructed. Analysis of stability conditions for the complete observer is made and a design procedure based on linear matrix inequalities is devised. A simulation example is also given for an open loop model
