This paper investigates the stabilization problem for Takagi-Sugeno fuzzy systems subjected to both fixed state delays and unknown time-varying output delays. First, a novel fuzzy observer is proposed to synchronously estimate the system state and the disturbance term caused by the unknown output delays. Then, along with the fuzzy observer, a fuzzy controller is designed to ensure the stability of the overall system by Lyapunov-based analysis. Finally, the effectiveness and correctness of the obtained results are verified by simulation example.
