Actuator fault estimation using optimization-based learning techniques for linear parameter varying systems with unreliable scheduling parameters
(Elsevier, 2024-01-01)
Article
Restricted access - publisher's policyA novel fault diagnosis procedure is proposed in this paper to estimate faults using a linear parameter varying (LPV) model whose scheduling parameters depend on the fault. A wrong determination of the operating conditions ... -
