Studies on Variable Cross Feedback Method of Chaos Control to PO Reaction

The variable cross feedback（VCF）method is proposed to control the nonlinear chaos system. The control principle is introduced，and the Peroxidase-Oxidase（PO）system is taken as a typical example to demonstrate the effectiveness of this method. The dynamical behaviors of the PO system controlled using the VCF method are given by computer numerical simulation. The results show that the return map of the system can be changed into the finite isolated points from the assemblage of discrete points having regular distribution and structure by appropriately
