    In chapter 6, with the results of above chapters, we discuss the optimal control problems for weak-smooth system and draw a conclusion coinciding with that of smooth system, i.e., the Pontryagin's maximum principle (see Th 6.2.7).
    第六章,在以上各章结果的基础上,研究了弱光滑系统的最优控制问题,得到了与光滑系统一致的结果——庞特李雅金类型的最大值原理(即定理6.2.7)。
    around the bifercation point of the doubling period from period 1 to period 2,the orbit of period 2 is not perpendsculor to the path of period 1, and the chaos is reached by jumping from orbit 6 directly.
    例如,与光滑系统中典型的倍周期分岔不同的是,在周期1到周期2的倍周期分岔点附近,周期2轨道分枝不垂直于周期1轨道分枝,并且直接经周期6到达混沌态.
    The weak differential system and the optimal control problems
    弱光滑系统的最优控制理论

    外加正弦驱动力抑制一类分段光滑系统的混沌运动
    Especially we put forward a conception of "weak-smooth system", and this paper is mainly to discuss -the optimal control problems for weak-smooth system.
    特别是提出了弱光滑系统概念,本文的主要目标就是讨论该系统的最优控制问题。
    With the conception, and example of " system", we see that the weak-smooth system not only exists, but also genuinely contains the systems discussed in many literatures(and we call these systems as "smooth system").
    从弱光滑系统的概念及该章给出的Немыцкий系统的例子,可以看到弱光滑系统不但存在,而且真包含许多文献讨论的系统(本文称为“光滑系统”)为特例;
    Hence, the optimal control problems for weak-smooth system includes the relevant ones forsmooth system, and thus concentrates the scattered problems and the deliberations--such asinfinite time interval, unbounded controls,and function in system not being F-differentiable,etc.
    进而,弱光滑系统的最优控制问题就包含了光滑系统的有关问题,其结果也使当前对一些零散的问题的研究——包括无限时域和无界控制问题等——得到了统一。
    Especially, we discuss the patch perturbations for a system that the function is only G-differentiable but not F-differentiable. This lays a foundation of discussing the optimal control problems for weak-smooth system.
    特别是首次对一类G-可微、但不为F-可微的系统的讨论,为下一章研究弱光滑系统最优控制的最大值原理奠定了基础。
    In Chapter three, the system investigated is an electronic circuit with over-voltage protection. A "quasi-dissipative and discontinuous" bifurcation, or a so-called "enhanced grazing" bifurcation can be produced in it by varying a characteristic parameter.
    所谓的“擦边”(grazing)分岔是上世纪八十年代在冲击振子模型中发现的,表征系统在一个特征参数的阈值从一个处处光滑的系统突变为一个不光滑的系统,突变的临界点对应于冲击碰撞的“擦边”情况,因此现在这种同时还伴随着类耗散性出现的“擦边”分岔也许还可以称为“增强擦边”(enhanced grazing)分岔。
    -3.The existence of the of the system's generalized solutions and the sub-system's solutions and the continuity of the solutions to the identification variable are proved using the theories of the partial-differential equation's solutions and the existence of the piecewise-differential system's solutions.
    3.根据偏微分方程定解问题理论以及分片光滑系统的解存在性理论,证明了系统广义解的存在性、子系统解析解的存在性以及解对控制变量的连续性。
    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.

    Catastrophe theory can effectively solve catastrophe problem that can possible appear in continuum system.
    突变理论能比较有效地解决光滑系统中可能出现的突变问题。
    Controlling chaos by the view of synchronization is studied,for dc-dc buck converter is a piece-wise smooth system. A buck converter that is in chaos can be synchronized with another that is in periodic state by using adaptive control method,which leads the chaotic buck converter from unstable state to stable periodic state so as to control chaos in this kind of circuits.
    从同步的角度研究了dc-dc buck开关功率变换器这种分段光滑系统中的混沌控制问题,采用自适应控制方法,使两个分别工作在混沌状态和周期状态的buck变换器达到同步,即将其从混沌区引导到稳定的周期区,达到抑制该类电路中的混沌的目的。
