Abstract: The robust control problem of nonlinear interconnected descriptor systems was discussed using T-S fuzzy descriptor model. A fuzzy state model for nonlinear interconnected descriptor system was presented by fuzzy modeling approach. A fuzzy decentralized controller design method was given on the assumption that the system was solvable. The robust stability of the closed-loop system with modeling errors was analyzed. On the basis of LMI, a sufficient condition was obtained. By using the property of weight value and fuzzy rules, less conservative LMI design approach was employed to establish fuzzy decentralized feedback controller. The design procedures and the effectiveness of the designed controller were illustrated by simulation.
