【Abstract】 We have proposed a project on controlling chaotic systems by the time delayed feedback.Via the analysis of emerging Hopf bifurcation of the system, analytic conditions for the low dimensional continuous autonomous chaotic system controlled by this project was given theoretically. Applying the conclusions we obtain for practical systems, it is shown, by theoretical description and numerical calculation, that the effectiveness and quality of control can be improved obviously and the analytic results are in accord with the numerical results.更多还原
