| Abstract: | The controller synthesis problem of uncertain systems with time varying delay is investigated. A robust controller with delay compensation is proposed based on Lyapunov function method. The stability criterion of the closed loop system, which is dependent on the size of the time delay and the size of its derivative, is derived in the form of linear matrix inequalities (LMI). Example shows that the results of using the method in this paper are less conservative than the existing ones. |
