A Combined Qualitative / Quantitative Approach for Fault Isolation in Continuous Dynamic Systems

  title={A Combined Qualitative / Quantitative Approach for Fault Isolation in Continuous Dynamic Systems},
  author={Eric-J. Manders and Sriram Narasimhan and Gautam Biswas and Pieter J. Mosterman},
The TRANSCEND system for fault detection and isolation in continuous systems uses qualitative reasoning methods to analyze transients caused by abrupt faults. Qualitative transient analysis avoids some of the computational difficulties associated with numerical schemes, but they lack discriminating power. This paper presents the formal basis for qualitative transient analysis, and then establishes the limits of the discriminatory power of this methodology. An integrated scheme that starts with… CONTINUE READING
