To some special ones...aquarius always be prone to keeping distance, because in his heart it's not the best thing to become couples just for the human needs...so to the special one, he always hope that the relationship between them should be last forever, once they go beyond the friendship limit, maybe some day, their affection will fade....then...how pity it will be...for the sake, aquarius would rather look at him/her silently at a long distance than fall in love with him/her, only by which their relationship can last forever....

对于有些人，瓶子始终是舍不得，舍不得因为男女之情跟他在一起。因为这个人，瓶子觉得跟他的相处应该是一辈子的事情，如果真的成为男女朋友，也许哪一日，感情褪色而分手。那样，该多遗憾。于是，瓶子宁愿永远这样默默的看着他，地老天荒，却无声也无言。我觉得后边的解释。。。更像是说，喜欢保持距离。。。so。。。。

The main contents are as follows.1 For the state control problem in closed quantum systems, according to the distance between states, the error between states and the average value of an imaginary mechanical quantity, three Lyapunov functions are chosen, respectively. The corresponding control law designs and the convergence analyses are studied. Especially, for the Lyapunov function based on the distance between states, a class of control laws that can solve the problem that an initial state is orthogonal to a goal state is designed. The convergence of the system is analyzed via LaSalle\'s principle and one method to find the largest invariant set of the closed loop system is proposed by linearizing the unitary evolution operator at the corresponding instants.

在这一背景下，本论文在指出研究量子系统控制的必要性、回顾量子系统控制理论和方法的研究现状的基础上，从控制理论的角度研究Lyapunov理论和最优控制理论对于封闭量子系统的应用以及开放系统中的若干问题，主要内容包含以下几个方面。1针对封闭量子系统中的状态控制问题，根据状态间的距离、状态间的偏差、一个虚拟力学量的均值，分别选择三种Lyapunov函数进行相应的控制律设计和收敛性分析。
