摘 要： 偏移和漂移故障是传感器故障的主要类型，本文建立一个单区域AHU模型，分别分析回风传感器在两类故障情况下的室内温度变化，并采用主元分析和递推主元分析方法，进行故障诊断的分析。结果表明，主元分析诊断及时，递推主元分析具有较好的容错性能。 关键词： 空气处理机 传感器故障 故障诊断 主元分析 递推主元分析 AHU Sensor Detection Using Principal Component Analysis and Recursive Principal Component Analysis Hu Yunpeng1 Chen Huanxin2 Xie Junlong2 Zhang Di2 Sun Chao2 1 Huazhong University of Science and Technology, School of Environment Science and Engineering; 2 Huazhong University of Science and Technology, School of Energy and Power Engineering Abstrcact: Bias faults and drifting faults are two of the most popular sensor faults in HVACrsquo;s concluded that the PCA method can detect the fault rapidly and the RPCA method should be more tolerant.
