Studies on model-based fault isolation methods for LTI processes and some new results

Problems related to fault isolation in dynamic systems are investigated. The first part of our study concerns the discussion on the existence conditions for a perfect fault isolation and the relationships between the fault isolation and disturbance decoupling problems. The second part is devoted to the presentation of a number of approaches to a (perfect) fault isolation. Finally, a study on the fault isolation schemes using a bank of residual generators is carried out.
