Abstract

In this paper a new loss minimization control algorithm for inverter-fed permanent-magnet synchronous motors (PMSM), which allows to reduce the power losses of the electric drive without penalty on its dynamic performances, is analyzed, experimentally realized and validated. In particular, after a brief recall of two loss minimization control strategies (the "search control" and the "loss-model control"), both a modified dynamic model of the PMSM, which takes into account the iron losses, and a "loss-model" control strategy, are treated. Experimental tests on a specific PMSM drive employing the proposed loss minimization algorithm were performed aiming to validate the actual implementation. The main results of these tests confirm that the dynamic performances of the drive are maintained, and enhancement up to 3.5% of the efficiency can be reached in comparison to the PMSM drive equipped with a more traditional control strategy.
分析了一种用于永磁同步电机驱动的损耗最小化算法的DSP实现和实验验证
本文分析、实验实现并验证了一种新的变频永磁同步电动机(PMSM)损耗最小化控制算法,该算法可以在不影响电机动态性能的前提下降低电机的功率损耗。特别地,在简要回顾了两种损耗最小化控制策略(“搜索控制”和“损耗模型控制”)之后,本文讨论了考虑铁损耗的修正PMSM动态模型和“损耗模型”控制策略。采用所提出的损耗最小化算法在某永磁同步电机驱动器上进行了实验测试,旨在验证实际实现。这些测试的主要结果证实,驱动器的动态性能保持不变,与配备更传统控制策略的永磁同步电机驱动器相比,效率可提高3.5%。
