Ordering chaos of Chua´s circuit-A feedback control approach

Ordering or controlling chaos has in recent years attracted special attention from a number of research groups in the areas of nonlinear dynamics and control. The authors have developed a unified linear feedback control methodology for this purpose, which works well for many general chaotic systems. It has been shown that under certain conditions a chaotic trajectory can be guided to one of the unstable limit cycles of the dynamic system, provided that an appropriate feedback control is applied. This control technique is refined and applied to the well-known Chua´s circuit here, giving simpler implementation with even better results. A simple sufficient condition for the design of such a linear feedback controller is given, and the numerical simulation as well as the physical implementation of the design feedback control configuration are both illustrated
