Abstract :
This paper presents robust H2 controller design for a discrete-time uncertain fuzzy system with dynamic output feedback. Other than stability, an H2 cost constraint is also considered to refine the performance. Since a dynamic output feedback control problem is not a convex issue, the transformation from nonlinearity to LMI is included in this article. Finally, an example illustrates the proposed design methodology.
