Because of its introduction of mutation operator, this algorithm overcomes the problem where by particle swarm optimization (PSO) algorithm easily falls into local optimal value, with a low calculation accuracy. At the same time, the distribution and diversity of particles in the sampling process are improved through the mutation operation. The defect of particle filter (PF) algorithm where the particles are poor and the utilization rate is not high is also solved. The mutation control function makes the particle set optimization process happen in the early and late stages, and improves the convergence speed of the particle set, which greatly reduces the running time of the whole algorithm. Simulation experiments show that compared with PF and PSO-PF algorithms, the proposed NPSO-PF algorithm has lower root mean square error, shorter running time, higher signal-to-noise ratio and more stable filtering performance. It is proved that the algorithm is suitable for real-time filtering and noise reduction processing of nonlinear signals. <\/jats:p>","DOI":"10.1142\/s0218001420580124","type":"journal-article","created":{"date-parts":[[2019,11,13]],"date-time":"2019-11-13T08:01:34Z","timestamp":1573632094000},"page":"2058012","source":"Crossref","is-referenced-by-count":91,"title":["Particle Swarm Optimization Algorithm with Mutation Operator for Particle Filter Noise Reduction in Mechanical Fault Diagnosis"],"prefix":"10.1142","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2706-0738","authenticated-orcid":false,"given":"Hanxin","family":"Chen","sequence":"first","affiliation":[{"name":"School of Mechanical and Electrical Engineering, Wuhan Institute of Technology, Wuhan 430073, P.\u00a0R.\u00a0China"},{"name":"Hubei Provincial Key Laboratory of Chemical Equipment, Intensification and Intrinsic Safety, P.
