Abstract

This article presents a dual-winding permanent magnet generator (PMG) system with integrated dual-channel controller to meet the requirements of high power density, high reliability, and high output performance of aircraft electric power system. The dual-winding of the PMG are designed to have the same phase spatially, with which the same rotor position can be applied in independent vector control. In addition, a dual-channel controller is applied to control the two sets of windings, which achieves high-performance control under normal state and fault-tolerant control under fault state. The integrated dual-channel controller integrates two sets of main power circuits into one controller and uses a main control unit, which simplifies the PMG system leading to reduction in the overall volume and weight. Reliability analysis of dual-winding PMG system is proposed to be compared with that of the single-winding PMG system. A dual-winding cooperative control strategy and a fault-tolerant control strategy are proposed to achieve high-performance control of DC-link voltage under normal condition and redundant functions under fault condition. As a result, the reliability of the PMG system is improved. The experimental results validate the effectiveness of the proposed PMG system and the control strategy.

带集成双通道控制器的双绕组永磁发电机系统研究

本文介绍了一种集成双通道控制器的双绕组永磁发电机系统，以满足飞机电力系统对高功率密度、高可靠性和高输出性能的要求。永磁发电机的双绕组在空间上具有相同的相位，因此可以对相同的转子位置进行独立的矢量控制。此外，还采用了双通道控制器来控制两组绕组，从而实现了正常状态下的高性能控制和故障状态下的容错控制。集成式双通道控制器将两套主功率电路集成到一个控制器中，并使用一个主控制单元，从而简化了永磁发电机系统，减少了整体体积和重量。提出了双绕组永磁发电机系统的可靠性分析，并与单绕组永磁发电机系统进行了比较。提出了双绕组协同控制策略和容错控制策略，以实现正常情况下对直流链路电压的高性能控制和故障情况下的冗余功能。因此，永磁发电机系统的可靠性得到了提高。实验结果验证了所提出的永磁发电机系统和控制策略的有效性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
