Fault Diagnosis Based in Fractional Observers

Fractional diagnosis is a fundamental subject for system monitoring. In this work we implement four fractional observers to able to asses faults of a fractional nonlinear system and a FHPS (fractional-order horizontal platform system) mechatronic device which gives us a real application model. We implement in this work estimation of faults and a comparison is made among the fractional estimators implemented, with an operational index function. Presumed on this operational index, a comparison was made among fractional estimators, and verify which one performed the best. We distinguished four fractional estimators, choosing the estimator gains to obtain and designate the best performance of each and every estimator.
