“…Chaos control, an important topic in nonlinear dynamical science (Dou, Sun, Duan, & Lü, 2009;Tao & Yang, 2008;Yang, Tao & Wang, 2010) and is one of the main features of chaos applied in practical engineering (Yassen, 2003;Zhu, 2009;Zhu & Chen, 2008). and its play a very important role in the study of dynamical systems and has great significance in the application of chaos.…”
