摘要:
提出一种面向机械故障诊断非线性振动信号特征提取及实时滤波降噪的新型粒子群优化粒子滤波(NPSO-PF)算法,是基于带变异算子的粒子群优化粒子滤波算法。应用变异控制函数和操作算子,通过改善粒子滤波(PF)算法粒子贫乏、利用率不高等问题,加速粒子集收敛,减少整个算法运行的时间。仿真结果通过与PF算法和PSO-PF算法相比,论证了提出的NPSO-PF算法具有更低的均方根误差、更短的运行时间、更高的信噪比和更稳定的滤波性能。
Abstract:
A novel particle swarm optimization particle filter (NPSO-PF) algorithm was proposed for the real-time filtering noise reduction of nonlinear vibration signals and feature extraction in fault diagnosis of mechanical system. The particle filter (PF) algorithm was optimized by the particle swarm with the mutation operator, by use of the mutation control function and operator to improve the problems of particle poverty and low utilization rate. The convergence of the particle sets is accelerated, and the running time of the proposed algorithm was reduced. By the comparisons of PF, PSO-PF and NPSO-PF algorithms, the simulation results show that the proposed NPSO-PF algorithm has the advantages of being less root mean square errors, shorter running time, higher signal /noise ratio and with more stable filtering performance.
