| Abstract: | Nevertheless,the most significant advantage of principal component analysis(PCA) is that no precise process model is needed,the development of capacity for fault diagnosis based on PCA is restricted to some extent.Based on the fault reconstruction technology,the fault diagnosis issue is explored by using T2 index.The theoretical conditions of fault reconstruction are obtained in principal component subspace.The fault identification index and diagnosis arithmetic are presented.Through the simulation monitori... |
