基于微分代数系统模型的同步发电机非线性鲁棒控制(论文17000字)
摘要:本文将鲁棒控制理论应用在电力系统中,针对同步发电机的非线性微分代数系统,设计了鲁棒控制器。首先,先对数值型案例进行分析,在非线性标称系统的基础上,加入不同类型的干扰信号,并通过MATLAB的仿真结果验证反步控制方法在鲁棒控制领域的可行性与适用性。然后针对同步电动机的三阶实用模型,根据干扰信号的类型以及出现位置的不同,通过运用反步鲁棒控制方法,推导出使相应的控制器使同步发电机维持平衡状态。最后利用MATLAB对同步发电机的案例进行仿真并进一步研究分析。

The nonlinear robust control of synchronous generator based on differential algebraic system equation
Abstract: In this paper, the robust control theory is applied in electrical power system. In allusion to the differential algebraic system equation derived from the synchronous generator, a robust controller is designed. First of all, On the basis of nonlinear nominal system, adding different kind of noise interference to prove that backstepping control approach is practical and adaptable in the field of robust control by using MATLAB simulations. In addition, In allusion to the three-order differential algebraic model that describe the synchronous generator, using backstepping control approach to design the different controllers that can deal with the problem caused by different kind of the noise factors and the different location it appears to keep the whole system stable even if the system has noise factors. Finally, doing further research and analysis on the simulation achieved by using MATLAB.
