摘要

This paper presents a robust fuzzy controller for nonlinear and uncertain system in continuous time described by the T-S fuzzy model. In this approach we used a PDC fuzzy controller built on the time-Varying Fuzzy Sets (VFS) based on a function depending on the error which characterizes the movement of the midpoint of the universe to the left or to the right. To achieve this objective, we use a decay rate controller and relaxed stability conditions for a nonlinear system.
