摘要: 借助最优控制混沌动力特性的方法,仅通过最优过程中的可调小参数的瞬态干扰反馈,将非稳态非线性油膜力作用下的不平衡转子系统出现的混沌运动,引导到嵌入在混沌吸引子内无数不稳定周期轨中预期的一个轨,并使之稳定。数值结果表明动态油膜—转子系统中的混沌运动也是可以有效控制的。

Abstract: Base on the optimum method of controlling chaos dynamical behaviors, by the feedback of transient small accessible parameter perturbations in optimum control process, chaos in the unbalanced flexible rotor system with the nonlinear unsteady-state oil-film force is rapidly directed to a expectative orbit of an infinite number of unstable periodic orbits which are embedded within the chaotic attractor and stabilized, The numerical result shows that the chaos in the dynamical film-flexible rotor system is also to be able to control efficiently.

Key words: Chaos, Control Parameter perturbations, Dynamicalfilm, Rotor
