Prediction-control based feedback control of a fractional order unified chaotic system

Based on a prediction-control scheme, a new strategy for stabilizing unstable fixed points of fractional chaotic system is proposed in this brief paper. The control price is low, since the designed controller will be set on only when the trajectory approaches near to the target according to the so-called ergodicity of chaotic system. Numerical experiments are also provided to verify the rightness of our scheme by taking the unified chaotic system as an illustration.
