Abstract:Aiming at the problem that the timedelayed feedback parameters are not easily confirmed,this paper presented a control scheme, i.e., timedelayed feedback control through the selfadapted method of adjusting feedback coefficient, to control the nonlinear Lorenz chaotic system .Numerical simulation results showed that the unstable periodic orbits of the system could be ballasted, the chaos could be eliminated via choosing proper delayed time and gain coefficient, and the system could be changed from unstable to stable. Because the additional reference signal is not necessary, and because the control actions can be exerted at any time in the chaotic state, so the presented method is simple and easy to implement. At the same time, the presented control scheme was applied to the control of animation, and the various cartoon roles could be controlled and moved along chaotic orbits or a certain special track.
