Popis:	The particle's trajectory in particle swarm was fully analyzed in this paper, the theorem about necessary condition of convergence property of PSO was proposed by solve difference equation. Based on this theorem, discussed the influence of random parameters on particle's trajectory, the concept of cluster-degree was put forward and distribute status of particle with different cluster-degree was studied. The reasonable parameters setting range based on cluster-degree was proposed, at the same time, velocity compensation of particle's velocity was proposed in order to improving performance of PSO. So this paper is helpful for the choosing and adjustment of PSO parameters in practical application.
