| Abstract: | By using a method of variable delaying feedback,the chaos of an optical SHG system is controlled effectively.The controllable parameter's regions are located with a analysis of maximal Lyapunov exponent (MLE) of the system,it is found that suitable delay and feedback stiffiness can make chaos is controlled so as to stabilize the system.The orbits of the controlled system are unstable periodic orbits in the chaotic attractor of initial system. |
