Abstract

This study presents a stability condition for a guaranteed cost sampled-data fuzzy control problem of non-linear systems. A Takagi-Sugeno (T-S) fuzzy model is adopted for the non-linear system and the sampled-data fuzzy controller is designed for a T-S fuzzy system. To develop the guaranteed cost control, a new stability condition of the closed-loop system is guaranteed in the continuous-time Lyapunov sense, and its sufficient conditions are formulated in terms of linear matrix inequalities. Based on the stability condition, the guaranteed cost control is considered and minimised for the closed-loop system from the continuous-time cost function. Finally, numerical examples are provided to verify the effectiveness of the proposed technique.
