| Abstract: | The controllers design and the stability analysis of retarded systems via linear Takagi-Sugeno(T-S) fuzzy models approach were discussed.First,the T-S fuzzy models with time-delay were presented and the stability conditions were derived by using Lyapunov functional approach.Then a stabilization approach for nonlinear retarded systems through fuzzy state feedback controllers was proposed.And the sufficient stability conditions for the closed-loop systems were derived.The simulation shows the feasibility of the approach. |
