摘要：
In this article, a Takagi-Sugeno fuzzy model is applied to deal with the problem of observer-based control design for nonlinear time-delayed systems with fractional-order a E (0, I). By applying the Lyapunov-Krasovskii method, a fuzzy observer-based controller is established to stabilize the time-delayed fractional-order Takagi-Sugeno fuzzy model. Also, the problem of disturbance rejection for the addressed systems is studied via the state-feedback method in the form of a parallel distributed compensation approach. Furthermore, sufficient conditions for the existence of state-feedback gains and observer gains are achieved in the terms of linear matrix inequalities. Finally, two numerical examples are simulated for the validation of the presented methods.
