| 摘 要： | 主导度是现代控制理论降阶处理中提出的物理概念，其内涵了系统特征值及可控性、可观性的分析，如果利用主导度分析评估调节系统的动态特性，则较单纯运用特征值的分布形态进行分析更为准确，以调节器模型－同步发电机励磁调节系统为例，推导出该系统对应的主导率表达式，并说明如何运用主导度评估其动态特性。

| Abstract: | The dominant degree is a physics concept in modern control theory to lowering the order of dynamic equation,it involves the analysis of characteristic value,controllability and observability of dynamic system.Using this method to analyse and to evaluate the dynamic characteristic of regulation system,it may be more accurate for analysis as compared with characteristic value distribution method.With excitation regulation system of generator as an example,the expression of dominant drgree is introduced,it shows that how to evaluate the system dynamic characteristic with dominant degree. |
