Abstract

A multiphase machine is more reliable than a three-phase one, but it usually shows reduced performance under faulty behaviour. In this paper, the performance in case of open-phase fault is analyzed, and two fault tolerant control algorithms, which aim to minimize the Joule losses in the remaining healthy phases, are compared. The proposed control techniques are validated by numerical simulations, and to prove their effectiveness some experimental results are presented. The experimental tests have been carried out on a quadruple three-phase induction machine, fed by four independent inverters, developed for More Electric Aircraft (MEA) applications.
四三相感应电机开路故障容错控制技术比较
多相电机比三相电机更可靠,但在故障行为下,多相电机的性能通常会降低。本文分析了系统在开相故障情况下的性能,并对两种容错控制算法进行了比较,以最小化剩余健康相位的焦耳损耗为目标。通过数值仿真验证了所提控制方法的有效性,并给出了一些实验结果。实验测试是在一个四三相感应电机上进行的,由四个独立的逆变器供电,为多电动飞机(MEA)应用而开发。
