Now the controllability theory in linear systems over the field R of real numbers has been heavily studied. This theory is efficacious for analyzing the characters which are determined by the value of physical parameters and system structure, nevertheless a practical system has a definite structure and has approximate, even unknown parameter sometimes because of a limit to experiment conditions, or a limit to making technology, the errors of observation. It is inconvenience for a linear system over the field R of real numbers to analyze the structure characters of a physical system, such as structural controllability.
目前,实数域上的系统的完全能控性理论研究已经很成熟了,它用于分析系统结构和物理参量的值共同决定的那些性能是有效的,然而,在工程中,由于实验条件或者制造工艺上的限制和观测上的误差,以及人为地对数据的近似处理,一个实际系统往往其结构是确定的,而参数只是近似的甚至未知的,实数域上的系统不便于分析物理系统的结构性质,如结构能控性。

The five characteristics of the system are exploiting the ordered decomposition of problems in the structure of networks; using the Hasse graph to map the transfer network to the field of real numbers homomorphically; distinguishing the production rules as strong rules and weak rules; using the method of scheduling among stations to balance the search by weak rules in every station; searching in the best-first way both in the large and in the small, but with the different aims respectively, which can be regarded as a BF′-BF strategy in which the macro guides the micro.
该系统有五个特点:利用了一种网络结构的有序分解;采用Hasse图将中转站网络同态地映射到实数域上;将产生式规则区分为强规则和弱规则;采用站间调度的方法系统地平衡了各站弱规则的搜索;全局和局部都为最佳优搜索,只是目标指向不一样,是一种宏观引导微观的BF′-BF混合策略。
