摘要:

本文提出了一种基于ESO和逆推法相结合的同步发电机非线性鲁棒励磁控制方法。通过构造ESO对模型不确定部分进行补偿,并保留了模型中有利于运用逆推法设计的非线性部分。利用逆推法对补偿后的系统进行严格的稳定控制律设计。整个系统的设计问题转化为若干低阶子系统的设计,逐步利用李亚普诺夫函数得到使整个系统渐进稳定的反馈控制律。通过仿真验证,该方法鲁棒性强,参数易于选取,具有良好的静、动态品质。

In this paper, the nonlinear robust excitation control of synchronous generator based on the ESO and back- stepping method is proposed. The model uncertainties are compensated by constructed ESO, and the nonlinear parts of the model are retained for using back-stepping design method. Stability control of compensated system is designed us-ing the method of back-stepping. The whole system problem is resolved into low order subsystems design. A simulation case study has carried out on one single machine infinitive bus system by using the Matlab/Simulink software platform. The proposed method has strong robustness, its parameters are easy to select, and static and dynamic characteristics have been verified.
