确定性系统

• However , the fact that stochastic motion exists in a fixed system goes against the traditional physical theory of deterministic
  而确定性系统中竟然存在着随机运动(类随机) ，这是与物理学传统的确定性(决定性)观念相悖的。
• A new technique for deriving high robust time delay filter using zero - placement was proposed in discrete time - domain to reduce residual vibration in an uncertain system
  摘要采用了零极点配置方法来设计具有强鲁棒性的时滞滤波器，消除小阻尼不确定性系统的残留振动。
• For stochastic systems with uncertain parameters in practical situations of industrial production , designs of adaptive controllers are based on theories of stochastic systems
  针对实际工业生产过程中不确定性系统的控制问题，必须采用随机系统理论和方法进行分析和处理。
• Chaos is a kind of seemingly random , chance or irregular movement , which appears in a definiteness system . it is a property token of non - linear system
  混沌是发生在确定性系统中貌似随机的无规则或不规则运动，它是非线性系统的一种性能表征，在工程中有着广阔的应用前景。
• Pwm series type of dc - dc converter is a strong non - linear , uncertain system , and due to the characteristic of itself , control and research of dc - dc converter become more difficult
  Pwm型dc - dc变换器为强非线性、时变和不确定性系统，由于其自身的特点使得dc - dc变换器的控制研究变得比较困难。
• Interval system is one land of uncertain systems whose partial or whole parameters vary within fixed intervals . uncertainties will affect systems " stability and other performances directly
  区间系统是一大类不确定性系统，其不确定性表现为系统模型的部分或者全部参数在各自固定的区间内波动。
• However there are some signals different from the two poles , named chaotic signals , which are generated by a determinate system but acting similar to stochastic signal and can not be forecasted in long term
  而混沌信号有别于这两大类信号，它由确定性系统产生，但行为却貌似随机信号，具有长期不可预测性。
• Chapter two introduces mathematical definition , the basic characteristics , and analytical and numerical methods of chaos in both deterministic and stochastic systems
  第二章，介绍了确定性系统混沌的定义和基本特征及其研究的解析方法和数值方法，并在此基础上引入了随机系统中混沌的定义、基本特征及研究方法。
• Neurocontrol is a branch of robot control . it presents a new approach to controlling complexly unlinear , dispersing and uncertainty systems . neurocontrol is successfully applied in lots of control systems
  它是智能控制的一个分支，为解决复杂的非线性、分散性和不确定性系统的控制问题开辟了一条新的途径。
• In the first part of the thesis , we generalize the unified approach to the evolutionary random response problems of a deterministic system ( the unified approach in brief ) , to a random linear system in the following ways
  论文前一部分将确定性系统中的统一解法，全面推广到随机线性系统中去，具体地作了三个方面的工作。
