Multi-parameter fault isolation using trajectory-based envelope

Parameter interval based fault isolation for single parameter fault has ideal isolation speed, the fault parameter value is estimated when fault is isolated. Analogous scheme can be built for multi-parameter fault isolation using envelope to replace scalar threshold for interval judgment. However wr...

Summary:Parameter interval based fault isolation for single parameter fault has ideal isolation speed, the fault parameter value is estimated when fault is isolated. Analogous scheme can be built for multi-parameter fault isolation using envelope to replace scalar threshold for interval judgment. However wrapping effect should be considered when envelope is used. In this paper a multi-parameter fault isolation scheme is built using a trajectory-based envelope which is without of wrapping effect.
