Abstract: This paper is concerned with chaos control for a modified Sprott E system. Applying time-delayed feedback control method, we establish some new conditions to control chaotic behaviour of modified Sprott E system. With the aid of local stability analysis, we theoretically prove the occurrences of Hopf bifurcation. Computer simulations are implemented to support analytical results. Finally, a brief conclusion is included.

Keywords: modified Sprott E system; chaos; stability; Hopf bifurcation; time-delayed feedback.
