“…Particle filters, also called as 'Sequential Monte Carlo Estimators', have been used widely in prognostics, peculiarly integrated in physics-based models. Some of the examples found in the literature are; fatigue crack propagation modelling for various engineering structures [28], [29], [30], [31], [32] and [33], battery capacity modelling [29], [34] and [35], centrifugal pump degradation modelling [36], thermal processing unit degradation [37], pneumatic valve modelling [38], DC-DC converter system level degradation modelling [39], Isolated Gate Bipolar Transistor (IGBT) degradation modelling [40], Proton Exchange Membrane Fuel Cells (PEMFC) life modelling [41], Lumen degradation modelling for LED light sources [42]. The list can be expanded to various engineering prognostic applications.…”
