To diagnose the fault in the Tennessee-Eastman(TE) process more accurately, a learning pseudo metric(LPM)-based case retrival method is proposed to replace distance measure retrieval method and a case-based reasoning(CBR) fault diagnosis model of TE process is established. Firstly, the LPM metrics are established to train the LPM model.Then, the similarity between the target case and each source case is measured to find the same type of cases as the target case. Next, the solution of the target case is obta...
