摘要
将粒子群优化算法(PSO)应用于平面度误差的优化计算中.应用实例表明,PSO能够很好地解决具有非线性优化目标函数或具有多参数的优化问题;PSO的计算精度优于最小二乘法的计算精度,与其他满足标准定义的最小区域条件的方法计算精度相当,能够获得精度较高的结果且简单易于实现.实例计算和理论分析证明算法是收敛的,其中理论分析条件:(1)惯性权重ω<1;(2)随机参数组合c>0;(3)2ω-c+2>0.
A novel method for flatness evalution based on particle swarm optimization （PSO） was proposed. The case study of computation shows that the PSO is very suitable for dealing with the optimization problems with nonlinear optimization goal function or with multi-parameters. The advantages are as following.. Its computation results are superior to those given by the least squared methods and as good as those given by other declared optimization methods; also it is efficient, easy to be understood and performed, and convergent verified by the computation and the theoretical analysis under the conditions of （1） inertia ω〈1, （2） random parameters combination c〉0, and （3） 2ω-c＋2〉0.
