 In this paper we present the analytic expressions of partition lines in the parametric space of a piece\|wise smooth mapping describing an electronic relaxation oscillator. The supercritical regions with permission of period\|doubling bifurcation, prohibition of period\|doubling bifurcation, and complete phase\|locking are discussed. Among them the region, where period\|doubling bifurcation is prohibited but chaos is permitted is reported for the first time to our knowledge. These kinds of phenomena and regions... In this paper we present the analytic expressions of partition lines in the parametric space of a piece\|wise smooth mapping describing an electronic relaxation oscillator. The supercritical regions with permission of period\|doubling bifurcation, prohibition of period\|doubling bifurcation, and complete phase\|locking are discussed. Among them the region, where period\|doubling bifurcation is prohibited but chaos is permitted is reported for the first time to our knowledge.

This paper deals with rub impacts of a rotor system with elastic case by using the method of Poincaré map. Two kinds of Poincaré map are constructed in order to study different characters of rub impacting motions, including the numbers of period and impact. It is found that the non smooth feature of piecewise smooth vector fields is very rich and complex. The rub impacting motions of the system are mainly chaotic, but periodic motions are also possible for parameters properly chosen, and various period windows are embedded in the chaotic region. The bifurcating rule of the system with the variation of case stiffness is also obtained through numerical simulations. It is shown that the rub impacts of the rotor system become even voilent as the case stiffness increases. As a special and simplified model, a constrained differential system describing rigid impacts of rotor systems are studied and some new results are shown. 分别采用两种不同的截面建立 Poincaré映射 ,对转子 -弹性机壳系统的碰摩运动进行了研究 ,得到了该类分段光滑系统运动的一般特点和转子碰摩运动随碰撞刚度变化发生分岔的规律。研究表明 ,该系统的碰摩运动主要以混沌形式出现 ,但不同的周期窗口按一定规律嵌入混沌区内。随着定子碰撞刚度增加 ,碰摩运动将会加剧。然后由该系统导出了刚性转子碰摩的约束微分系统 ,从而将碰摩转子系统的两种不同描述形式统一起来 ,并分析了周期刚性碰摩运动的分岔情况 In this paper, we introduce a weaker differential system that includes many control systems as special cases, and discuss the optimal control problem relevant to the system. 提出了弱光滑系统概念 ,并讨论了与之相关的最优控制问题 . << 更多相关文摘
