Chaotic systems controlled with perturbed parameters based on washout filter tec hnology

The chaos control methodology based on the washout filter technology is used in chaotic systems both without perturbation and with perturbed parameters. A sufficient condition on controller design with perturbed parameters is presented. Numerical results show that this method is easy to be implemented in engineering, requires little control cost, stabilizes the original unstable fixed points within the chaotic attractor and is robust enough. Thus, it is very suitable for engineering applications.
