To diagnose multiple faults of multivariate system, DCA (designated component analysis) is introduced to avoid the pattern compounding problem of PCA (principal component analysis). In this paper and a DCA based multi-level small fault diagnosis method is developed for multiple faults diagnosis when small faults are involved in the system. Simulation for observation data involved 4 faults shows its efficiency.
