摘要: Accurate online prognosis of engineering systems plays a vital role in and health management (PHM) technologies to ensure safety, prevent damage economic loss. The particle filter (PF) algorithm has proved be an effective method for prognostics. However, the PF suffers from serious degeneracy impoverishment problems. Most studies literature focus on solving problem but at heavy computational cost. In this study, we aim explore time efficient Partial Stratified Resampling which can used state estimation problems compare it with conventional algorithms. accuracy precision algorithms are validated using lithium-ion battery data sets CALCE® research group.
