Based on a method of Riccati matrix inequality,the problem of delay dependent feedback control with estimate delay is discussed for the linear time delay systems.

The mechanism for the action of delayed feedback control in a nonlinear system with external periodic forcing is investigated in this paper.

Combining with drive and delayed feedback control methods,a new asymptotic synchronization standard is proposed,in which,we can make the drive system and the response system achieve synchronization with two controllers.

Applying linear matrix inequalities (LMI) theory, the delay dependent stability condition is deduced.

Lyapunov functions combined with Linear Matrix Inequality (LMI) were used to derive, the sufficient delay dependent absolute stability and stabilization conditions for a class of Lur e uncertain time-delay systems with time-delay feedback either in states or the nonlinear part through introducing a new state transformation.

This paper studies the delay dependent memoryless robust stabilization problem for a class of uncertain linear system with time varying delays in both state and control.

For a class of chaotic systems which include Lur e systems and Lipschitz systems,the sufficient criterion for uniform sysnchronization under time-lag output feedback control is deducecd by Lyapunov function method.
