电励磁同步电机电压模型磁链观测器

Electrically excited synchronous motor flux model is usually observed current model and voltage model. Current model of the motor parameters and is sensitive to open-loop control of flux, Air-gap flux observation is not accurate. In this paper, several voltage model flux observer, Theoretical analysis of various voltage model flux observer principle. And compared the integral saturation and the integral value of the initial phase before the various voltage model flux observer effect. Finally, Matlab / Simulink simulation platform. Analysis of simulation results verify the theoretical results derived earlier.
