| Abstract: | The adaptive control for uncertain systems with time-delay is addressed in this paper.Firstly,the observer-based adaptive fuzzy controller is designed,then, the robust stability is analyzed with Lyapunov stability theory,and the sufficient stability conditions for closed-loop systems is proposed in the form of linear matrix inequalities(LMIs),observer gains and feedback gains can be gotten by solving a set of linear matrix inequalities.Finally,an example is given to illustrate the effectiveness the proposed... |
