Abstract: Aiming at some demerits of Particle Swarm Optimization(PSO), such as falling into local optimum, analyzing the evolutionary equation of particle swarm optimization, an improved particle swarm optimization algorithm is proposed. The algorithm uses different parameters in the oscillation, which is used to adjust the global and local search capabilities of the particle swarm algorithm. The experimental results of the test function and the robot path planning are compared and analyzed with the experimental results of standard PSO, two-order PSO and two-order oscillating PSO algorithm, which verifies the effectiveness and feasibility of the improved algorithm.

Key words: Particle Swarm Optimization(PSO), two-order oscillating evolutionary equation, convergence precision, robot path planning

摘要: 针对粒子群算法易陷入局部最优等问题,分析了粒子群算法的进化方程,提出了一种改进的粒子群优化算法。算法在振荡环节采用互不相同的参数取值来调节粒子群算法的全局和局部搜索能力,并通过对测试函数和机器人路径规划问题仿真模拟,与标准PSO、标准二阶PSO、二阶振荡PSO算法的实验结果进行对比分析,验证了所提出算法的有效性和可行性。
