In this scheme, the description of unitary evolution and quantum measurement is unified and the quantum control operation is represented by probability state transition. The algorithm works as follows. At first a measurement is applied on the system. If the state after collapse is not the desired eigenstate, then system evolution will go on. After a period of time, the system is measured again. The process will go on like this until we get the desired eigenstate by measurement. Finally the system is driven to the target state with admissible control as before.

4把本征态能控性概念进一步向前发展，提出了概率能控性的概念，将幺正演化和量子测量这两种量子控制手段统一的用概率状态转移来描述，并针对一类特殊的本征态能控的系统，提出了幺正演化和测量交替进行的量子反馈控制策略：如果单步测量所得到的本征态不是期望的本征态，则让系统以这一本征态作为新的初态进行下一步的幺正演化，然后在适当的时候再次测量，让系统塌缩到某一本征态，如此重复进行，直到达到期望的目标态为止。

First, one. analyzes the eigenstates-from reachable sets and seeks the one which the target state belongs to. Then using the Grover iteration to amplify the probability amplitude of the desired eigenstate (the modul square of which is the probability of the corresponding eigenstate that the system will collapse to when it is measured). By measuring, the system will then collapse to the desired eigenstate with a probability of almost unity. Finally, one can use the admissible control to drive the system from the eigenstate to the target state.

该策略的核心思想是对本征态能控的系统，通过分析控制目标态与本征态的关系，寻找给定目标态所属的本征态可达集，然后利用量子非结构化搜索的Grover算法，将任意给定的系统初始态经过一定次数的Grover迭代，放大该本征态所对应的概率幅(概率幅的模方对应测量时波函数塌缩到对应本征态的概率)，然后对迭代后的态进行一次测量操作，使系统以接近1的概率塌缩到所需的本征态(前面分析得到的本征态可达集所对应的本征态)，最后用容许的控制将系统从该本征态控制到期望的目标态。

The average desired velocity of the drivers has been assumed to be proportional to the instantaneous velocity by M ndez and Velasco when a alternative model was proposed. Based on this postulate, the desired velocity of a single driver delineates to be proportional to the local instantaneous velocity in this paper, which is a property of aggressive drivers who all want to drive with the maximum velocity. However, the deriver does not occupy this aggressive characteristic all the time.

基于M ndez 和Velasc关于司机平均期望速度与瞬时速度成比例的假设，认为个体司机的期望速度与其局域瞬时速度成比例，期望以更大的速度行驶，然而并非所有的司机都具有这样的进取特性，为了抑制司机这样的进取特性，引入适应性公式来近似表达单个司机期望速度随时间的变化率。

In order to damp the effect of aggressive characteristic of the drivers, the change with time rate of the desired velocity of a single deriver is approximately taken place of the adaptive function in the reduced Paveri-Fontana equation which describes that the instantaneous desired velocity of a single deriver arrives at the deriver' self-equilibrium velocity in the relaxation time.

适应性公式表明单一司机的期望速度在一定的驰豫时间内达到司机的自平衡速度，也就是当交通流处于平衡状态时，个体司机达到的期望平衡速度。

Persons who had high level of social dominance orientation prefered enhancing hierarchy, and desired that "inferior" groups should be more dominated by "superior" groups, while persons who had low level of social dominance orientation prefered attenuating hierarchy, and desired that 'inferior' groups wouldn't be dominated by "superior" groups.

高社会支配倾向者偏好加大不同群体间的阶层差异，并期望优势群体更多地支配劣势群体；低社会支配倾向者偏好缩小不同群体间的阶层差异以增加社会平等，并期望优势群体更少地支配劣势群体。

In this paper, we discuss the learning control for nonlinear discrete system with delay. It is not necessary to use the desired input corresponding to the desired output and the desired state corresponding to the system in our learning algorithm and in the process of learning control. Therefore, our method needs less dynamics information of the controlled object than previous ones and only the qualitative Lipschitz condition is required.

摘 要：讨论了滞后非线性离散系统的学习控制问题，由于所给的学习算法及学习控制过程中，没有涉及和用到相应于理想输出yd的理想输入ud及对应于系统的理想状态xd，故对被控对象的动力学信息要求得很少，只是一种定性上的Lipschitz条件。

There was a time when Krishnamurti, as an individual, desired to find Liberation, but, like all human beings, he was caught in the wheel of his own desires, of his own knowledge, of his own little conceits and deceits. Because he desired to reach that Truth which is the purpose of life, because he desired to destroy that separateness which existed between the Truth and his ignorance, he suffered, he was bound to the wheel of birth and death.
