A Multi-Fault Diagnosis Method for Sensor Systems Based on Principle Component Analysis
A model based on PCA (principal component analysis) and a neural network is proposed for the multi-fault diagnosis of sensor systems. Firstly, predicted values of sensors are computed by using historical data measured under fault-free conditions and a PCA model. Secondly, the squared prediction erro...
