In the on-line monitoring for the fault of rolling bearing, we have no information about the cluster number of the obtained data signal, which cause great challenges for on-line fault diagnosis when using clustering algorithms. In this paper, we extract three features of the vibration signals of rolling bearings as the parameters in time-domain, and then multi-scale possibilistic clustering (MPCM)...
The optimal test sequence design for fault diagnosis is a challenging NP-complete problem. An improved differential evolution (DE) algorithm with additional inertial velocity term called inertial velocity differential evolution (IVDE) is proposed to solve the optimal test sequence problem (OTP) in complicated electronic system. The proposed IVDE algorithm is constructed based on adaptive differential...
