| Abstract: | In this paper,a multiple fault diagnosis strategy based on most posterior probability candidate fault set replace method is put forward.Firstly the formalization of most posterior probability candidate fault set replace method is studied;then the two computational models are analyzed:single fault diagnosis and multiple fault diagnosis,and a multiple fault diagnosis algorithm of Binary Particle Swarm Optimization is presented.At last,according to an illustration,it is proved that the improved BPSO does to be... |
