Abstract: In this paper, the H 2 filtering of bilinear systems is considered using T-S fuzzy approach. For the bounded input, the bilinear system can be transformed to the Takagi-Sugeno (T-S) fuzzy dynamic system by putting the control input as the premise variable. Then the robust H 2 filter for T-S fuzzy system is designed upon existing results using the linear matrix inequality(LMI). The feasibility and effectiveness of the designed filter is shown in the numerical example section.
