Adaptive Feedback Control of Chua´s Circuit Chaos System

A feedback control method and an adaptive feedback control method are proposed for a class of simple 3D autonomous system, Chua’s circuit chaos system. The asymptotical stability is proven with Lyapunov theory for both two proposed control methods. The Chua’s circuit Chaos system can be stabilized to one of its three unstable equilibrium points respectively with the proposed control methods, and simulation results show that the proposed methods are valid and control performance is improved by introducing adaptive technology.
