Intermittent control of nonlinear systems with time-varying delay
Qin Zhen-ji · Journal of Computer Applications · 2011
Time-varying delay widely exists in nonlinear systems.This paper investigated the intermittent control problem of nonlinear systems with time-varying delay and its applications in chaotic secure communications.The authors proposed an intermittent control scheme,and analyzed its correctness theoretically.Moreover,a theorem was also given to determine the corresponding parameters in the controller.According to the proposed theorem,the synchronization of two chaotic Chua's circuits can be achieved by designing intermittent controller.The method was applied to chaotic secure communications,and the sender's signal could be recovered well at the receiving end after the synchronization was achieved.This also shows that the proposed method has some engineering applications.
