Abstract :
The paper solves the observer-based Hinfin control problems of T-S fuzzy systems. Two conditions that guarantee the existence of Hinfin controller based on fuzzy observers are developed. The conditions are more relaxed than the existing one and ensure the designed fuzzy controller achieving a better Hinfin control performance. A numerical example is given to demonstrate the validity and applicability of the proposed approach in the control of a nonlinear system.
