首发时间:2010-01-15
摘要:文章简要分析了基于电压模型的同步电机磁链观测器的原理,同时讨论了积分环节带来的直流偏置误差和初始值积分误差两个问题。本文提出采用MT轴系下负反馈可以有效地解决积分零点漂移,并采用小信号模型的方法来进行分析微小扰动时的观测器稳定性。

Stability Analysis and Control of Flux Estimation
Abstract:The principle of synchronous motor flux estimator based on voltage model is analyzed in brief, in addition, DC bias error and the initial value of integral error are discussed. This paper presents MT coordinate negative feedback can solve out integral zero drift, and analyzes the stability of estimator as small disturbance with small-signal model.
Keywords: synchronous motor flux estimation negative feedback small-signal model
