Owing to the classical Ott-Grebogi-Yorke(OGY) method can only stabilize to the unstable fixed point, an improved OGY method of chaos control, combining feedback control with OGY method, is proposed. The expression of feedback control is introduced into classical OGY method. The output signal with time delay is backed to the original system. The feedback system is controlled by the OGY method. The...
Owing to the original Ott-Grebogi-Yorke(OGY) method can only be applied to the discrete dynamical systems or continuous dynamical systems which can be described by Poincare mapping, a novel method for controlling chaos is proposed by resorting to echo state network. The network was trained by the input and output sample which were generated by OGY method. The chaos controller can drive the chaotic...
