H∞ dynamic output feedback control for T-S fuzzy systems with local nonlinear models

This paper considers the H∞ dynamic output feedback (DOF) control problem for nonlinear discrete-time systems, which are represented by a new type of T-S fuzzy systems with local nonlinear models. A class of DOF controllers with local nonlinear dynamic structures are proposed and a convex controller design method is developed. In contrast to the existing methods, the new method can design dynamic output feedback controllers with fewer fuzzy rules as well as less computational burden. A numerical example is given to illustrate the effectiveness of the proposed methods.
