Abstract: This paper presented the problem of decentralized static output feedback control for a nonlinear interconnected system which is composed by a number of Takagi-Sugeno( T-S) fuzzy bilinear subsystems with interconnections.Based on the decentralized control theory, some sufficient stabilization conditions were derived for the whole close-loop fuzzy interconnected systems. I}he stabilization conditions were further formulated into linear matrix inequalities(LMI)so that the corresponding decentralized controllers can be easily obtained by using the Matlab LMI toolbox. Finally, a simulation example shows that the approach is effective.
