输电系统发电机励磁自适应控制的研究

本文在对被控对象的结构特征分析后指出，当串并联自适应状态调节器的基本原理应用于发电机励磁控制时，不能保证自适应律是渐近超稳定的。为此，本文导出了改进的自适应律，并设计了自适应发发电机励磁调节器，利用最优控制来设计参考模型，计算机仿真给出了计算结果和响应曲线，并与常规控制以及最优控制进行了比较。

Researches on Adaptive Excitation Control of Synchronous Machine for Electric Power Transmission

This paper point out that an adaptive control law with gradual hyperstability characteristics can not be reached when the basic theory of series-parallel state regulator is used to excitation control according to the analysis of structure of controlled object. A new improved adaptive law is derived, with the improved adaptive law, an adaptive synchronous machine excitation control is designed. A model reference is offered by using optimal control theory. The results is given by computer simulation and the corn-parision is made with the conventional control and the optimal control.
