Abstract :
This paper investigates the stability and stabilization problems for a class of fuzzy large-scale system whose state variables are unavailable. T-S fuzzy model are utilized to approximate the nonlinear system, and an observer-based output-feedback controller is designed, some sufficient conditions of the closed loop system are derived based on Lyapunov function and in terms of a linear matrix inequality problem (LMIP).
