Abstract :
This research focuses on the stability analysis and controller design for nonlinear systems constructed by fuzzy input-output models (FIOMs), which are different from the conventional Mamdani and T-S types of fuzzy models. Some stability conditions based on the linear matrix inequalities (LMIs) are proposed to analyze the stability of the closed loop fuzzy system and synthesize a static compensator, which can guarantee the globally asymptotically stability of the equilibrium. A numerical simulation is provided to illustrate the effectiveness of the proposed stability conditions.
