摘要

针对磁链预测问题,基于广义比例积分观测器原理设计磁链观测器,并基于此实现具有误差校正的磁链预测,提升磁链预测精度;针对备选电压矢量较少的问题,构造一种均匀对称分布的正十二边形矢量集,不仅增加可选矢量数量,而且矢量集的正十二边形分布特征有利于特定次开关谐波的消除。基于以上核心算法,最终为风电系统中PMSG设计FCS-MPFC方案,并通过实验验证所提方案具有较强的参数鲁棒性和较高的转矩控制精度。

Abstract

As a result the control accuracy is not high. As to the flux estimation, the principle of the generalized proportional integral observer is used to design a stator flux observer, based on which the flux prediction algorithm,strengthened with error correction,is further developed. Consequently, the prediction accuracy is enhanced. To expand the candidate voltage vector set, a dodecagonal voltage vector set, with the candidate ends uniformly located on the twelve vertexes, is proposed, by which not only do the candidate vectors be enriched, but also the harmonics are allowed to be suppressed further due to the dodecagonal merits. With the core algorithms presented above, a FCS-MPFC scheme is developed for the PMSG in wind energy system. As shown by the experimental results, the parameter robustness is greater and the torque accuracy is higher.
