Sensor Placement for Fault Diagnosis Based on Casual Computations
This work develops a methodology to solve the sensor placement problem
for fault detection and isolation. The proposed methodology is
suitable to handle highly non-linear and large scale systems since it
is based on structural models. Furthermore, causality is assigned in
those variable-equation relations that the variable can be computed
from the equation in order to guarantee the computability of the
unknown variables in the residual generation design. Finally, the
developed methodology is applied on an air compressor model.
