| 摘 要： | 针对一类非线性Vanderpol-Duffing耦合振子机电系统,讨论了系统的基本动力学行为,运用非线性系统理论和Routh-Hurwitz定理分别对系统平衡点的稳定性作了研究,得到了相关的定理。同时采用自适应反步法,对含有6个未知参数的机电系统设计了相应的控制器。最后通过数值示例进行仿真,对文中论证进行了强有力地论证。

| Abstract: | This paper consider the dynamics and a problem of controlling chaos in a nonlinear electromechanical system which consists of the van der Pol oscillator coupled to the Duffing oscillator.The stability of the critical points is analyzed using the analytic Routh-Hurwitz criterion.And adaptive backstepping design is used to control the electromechanical system with six parameters unknown.Finally,give some numerical simulation studies of the system in order to verify the analytic results. |
