This paper presents output feedback stabilization condition for nonlinear using artificial Takagi-Sugeno (T-S) fuzzy systems. Continuous membership functions of the T-S fuzzy model are represented by staircase ones. Stabilization condition in terms of linear-matrix-inequalities (LMIs) formulation is derived using the artificial T-S fuzzy model and Lyapunov function. Controller gains of output feedback T-S fuzzy systems are obtained using LMIs solutions. Finally, simulation example is given to illustrate the merits of the proposed method.
