In engineering and technology, it is often demanded that self-oscillation.be eliminated.so that the equipment or machinery may not be damaged In this paper, a mathematicalmodel for reducing vibration is given by the following equations:(?)_1+(?)((?)_1) +k_1(x_1-x_2) =0, (?)_2+c(?)_1+k_2(x_2-x_1) =0 (*)We have discussed how to choose suitable parameters c_1, k_1,k_2; of equations (*),so as to make the zero solution to be of global stability. Several theorems on the globalstability of the zero solution of equations (*) are also given. 相似文献
