DeepConvolutionalTransferLearningNetworkANewMethodforIntelligentFaultDiagnosisofMachineswithUnlabeledData(深度卷积迁移学习网络:一种新的无标记机器故障智能诊断方法) 雷亚国团队2018年文章。 机械智能故障诊断的成功依赖于两个条件。1)含有故障信息的有标签数据是可用的。2)训练和测试数据是从相同的概率分布中获取的。然而,对于大部分机械,很难获得大量的有标签数据。此外,尽管一些机械可以获取有标签数据,但是由于数据分布的差异,用这些有标签数据训练的智能故障诊断方法可能无法对从其他机械获得的无标

The evolvable hardware (EHW) is widely used in the design of fault-tolerant system. Fault-tolerant system is really a real-time system, and the recovery time is necessary in fault detection and recovery. However, when applying EHW, real-time characteristic is usually ignored. In this paper, a fault-tolerant strategy based on EHW is proposed. The recovery time, predicted by the fault tree analysis (FTA), is considered as a constraint condition. A configuration library is set up in the design phas

Wind energy has been drawing considerable attention in recent years. However, due to the random nature of wind and high failure rate of wind energy conversion systems (WECSs), how to implement fault-tolerant WECS control is becoming a significant issue. This paper addresses the fault-tolerant contro
