Comparative study of inversion-based and observer-based approaches for fault diagnosis in DC-DC converters
(2017-07-07)
Recently, model-based approaches have been proposed for fault diagnosis as an emerging alternative to traditional techniques. Particularly, the inversion-and observer-based were proposed for fault diagnosis as successful ...
Fault section estimation in electric power systems using an optimization immune algorithm
(Elsevier B.V. Sa, 2010-11-01)
This paper proposes a methodology based on the unconstrained binary programming (UBP) model and an optimization immune algorithm (IA) to estimate fault sections in electric power systems. The UBP model is formulated using ...
