Coupled Feedback Control of Chaos in the Qi System

Abstract:

Article Preview

The complex dynamics behavior of the four-dimensional Qi system is studied. The route to chaos of the system is studied by the time course diagram, phase portraits and Poincaré maps. We use a Coupled feedback strategy to control the chaotic motion towards regular motion. Numerical simulation shows the effectiveness and feasibility of the strategy to get rid of chaos by stabilizing the related unstable periodic orbit. This control method can be applied to other chaotic systems.
