Sensor Placement for Fault Isolation in Linear Differential-Algebraic Systems
An algorithm is proposed for computing which sensor additions make a
diagnosis requirement specification regarding fault detectability and
isolability attainable for a given linear differential-algebraic
model. Restrictions on possible sensor locations can be given and if
the diagnosis specification is not attainable with any available
sensor addition, the algorithm provides the solutions that maximize
specification fulfillment. Previous approaches with similar
objectives have been based on the model structure only. Since the
proposed algorithm utilizes the analytical expressions, it can handle
models where structural approaches fail.
