Our approach is based on Takigi-Sugeno (T-S) fuzzy modeling method and variable structure control (VSC) technique. Thus, the problem of estimating the ASR of uncertain T-S fuzzy systems with bounded sliding mode controllers is proposed. To simplify the problem, we use a state transformation to reduce the system order of the T-S fuzzy systems. Then we design the sliding surface for the transformed system. Using the Lyaponov stability theorem, the ASR can be estimated. Simulation results are presented to verify the effectiveness of the proposed scheme. Advisor Committee Chung-Chun Kung - advisor
