CHAOS CONTROL OF A VIBRO-IMPACT SYSTEM WITH PARAMETER ADJUSTMENT

Ma Yongjing,Ding Wangcai,Yang Xiaogang(School of Mechanical Engineering,Lanzhou Jiaotong University,lanzhou 730070)  
Parameters adjustment and continuous feedback control strategy are studied,according to output variation of a vibro-impact system with clearance.The control law of parameters adjustment is given.The chaotic motion of the system can be directed into the stable objective period motion after a proper control strength vector is elected.This strategy is applied to a two-degree-freedom vibro-impact system.By numerical simulation,the effectiveness of the method is demonstrated.
