摘要
变频调速电机通过磁场控制进行效率优化的课题日益为人们所重视。本文从分析饱和对效率优化的影响入手,探讨基于线性模型进行效率优化控制的合理性及局限性。通过引入负载边界的概念,提出准效率最优控制方法。通过实验验证,得到了满意的结果。
Deals with the efficiency optimization in an adjustablefrequency induction motor drive by flux control. From the analysis of the saturation effects on efficiency optimization, the limited availability of a linear model optimum efficiency control is investigated. By introducing the conception of 'load boundary', a quasi-optimum efficiency control strategy is proposed with the theoretical results confirmed by the laboratory experiments.
