The purpose of this paper is to design the robust fault‐tolerant control FTC open‐circuit fault IGBT's, first of all. The modeling and control of the induction motor in the healthy inverter and in the faulty inverter (open‐circuit fault at the IGBT switch) are proposed. Furthermore, the technique for detection and location the open‐circuit fault an IGBT based on the Park vector combined with the polar coordinate. In order to ensure the service continuity of the system, two methods of tolerance are developed: the first method, the indirect vector control with H^∞ controller of the induction motor fed by a three‐phase inverter based on the fault compensation. The second method, the indirect vector control of the induction motor fed by a three‐phase inverter with the redundant leg. Finally, comparative study between the two techniques of tolerance is carried out. The performance of each technique is confirmed by experimental results.

使用H∞电流控制器的异步矢量间接控制IGBT开路故障补偿

本文的目的是首先设计鲁棒的容错控制FTC开路故障IGBT。提出了健康逆变器和故障逆变器（IGBT开关开路故障）中感应电动机的建模和控制。此外，基于Park矢量和极坐标的IGBT开路故障检测和定位技术。为了保证系统的服务连续性，容忍的两种方法开发了：第一种方法，用间接矢量控制ħ ^∞基于故障补偿的由三相逆变器供电的感应电动机的控制器。第二种方法是由带有冗余支路的三相逆变器供电的感应电动机的间接矢量控制。最后，对两种公差技术进行了比较研究。实验结果证实了每种技术的性能。
