This paper is devoted to the problem of controlling chaos in the Qi system. A time-delayed feedback control method is applied to suppress chaos to unstable equilibria or unstable periodic orbits. Using a local stability analysis, we theoretically prove that the Hopf bifurcation occurs. Some numerical simulations are carried out to support the theoretical predictions. Finally, main conclusions are drawn.
