摘要在(转夏，2006b)中提出的调速器的基础上，讨论了重载列车的容错控制问题。假设了列车的故障模式，研究了相应的故障检测与隔离方法。对FDI和重新设计的调速器的适用性进行了仿真试验。结果表明，在系统无故障时，容错控制不会明显降低调速器的性能，而在系统故障时，容错控制能明显改善调速器的性能。
Abstract The fault-tolerant control of heavy haul trains is discussed on the basis of the speed regulator proposed in (Zhuan and Xia, 2006b). The fault modes of trains are assumed and the corresponding fault detection and isolation (FDI) are studied. Simulation tests were conducted on the suitability of the FDIs and the redesigned speed regulators. It is shown that the proposed fault-tolerant control does not explicitly worsen the performance of the speed regulator in the case of a faultless system, while it obviously improves the performance of the speed regulator in the case of a faulty system.
