遍历马尔可夫链

With a suitable performance function and an initial control that made the closed system bounded, a serial of controls that made the performances better could be obtained by policy iteration, and ergodic Markov chains were constructed by the state serial with the corresponding feedback control.

在合适的性能指标并能找到一个使系统性能有界的控制的前提下，通过策略迭代可以求出逐步改善系统性能的控制序列，同时得到状态序列在相应反馈控制作用下构成遍历的马尔可夫链。

Markov chain: discret-time Markov chains, classification of states, ergodic, stationary distribution.

马尔可夫链：离散时间的马尔可夫链，状态的分类，遍历性，平稳分布。
