| Abstract: | In this paper,two-degrees freedom vibro-impact system is studied.Using damper coefficient feedback control of chaos,the chaotic motions of the system can be directed into stable period-1 orbit and period-2 orbit by choosing control gain coefficient properly.By numerical simulation,the effectiveness of the method is demonstrated. |
