Chaos control has become one of the hottest issues in the current control field. According to the nonlinear dynamic characteristics of chaotic system and the stability principle of delay system, this paper discusses the control and synchronization of the time-delay chaotic system. It intends to research the time-delay chaotic system with a new method and design a feasible linear controller to realize the time-delay chaos control and synchronization of the Lorenz system. At the same time, this algorithm can not only control the chaotic system with the unknown time delays effectively, but also be extended to a class of time-delay chaos with different time delays. Finally, the numerical simulation results verify the effectiveness of the proposed control algorithm.
