Abstract
According to the intelligent behavior of social population, the centroid of the individual best of particle swarm is firstly introduced in p article s warm o ptimization (PSO) model to enhance inter-particle cooperation and information sharing capabilities, then combining the m echanism of p opulation m igration a lgorithm (PMA) , a novel PSO algorithm with adaptive space mutation (PM-CPSO) is proposed to im prove computing performance of PSO algorithm. Experiment results of Benchmark function and practical application in quality monitoring of laser welding process show the new algorithm has not only higher convergence precision and faster convergence speed, but also can avoid the prema ture convergence problem effectively.
