摘要
研究了带线性恢复力和外力激励的Duffing-Van der Pol方程,该系统由未扰动系统经拟周期扰动而得.应用动力系统的分支理论,Melnikov方法,二阶平均方法和混沌理论,得到该系统的平均系统产生混沌的准则,数值模拟验证理论结果正确.
In this paper,a class of Duffing-Van der Pol equation with linear restoring and external excitations is investigated.The equation is deduced from unperturbed system under quasi-periodic perturbation.By applying bifurcation theory,Melnikov methods and second-order averaging method and chaos theories,the criterion of existence of chaos in averaged system are obtained,and numerical simulations show the consistence with the theoretical analysis.
