Based on Takagi-Sugeno(T-S) fuzzy models, the robust fuzzy filtering problem of discrete-time nonlinear stochastic delay systems is studied. Under the definition of stochastic stability, a LMI-based systematic designing scheme for robust fuzzy filter is presented, which guarantees the filtering error dynamic systems satisfy a prescribed l2-l∞ noise attenuation level for all energy-bound noise signals. The practical applicability of the proposed method is illustrated by a simulation example.
