摘　　要：将粒子群算法与传统的PID控制器相结合,并采用平方误差矩积分函数作为适应度判据,构成了PSO-PID控制器。以电液数字伺服双缸系统的PID参数优化为例,使用粒子群优化算法对PID参数进行优化。仿真结果显示:PSO算法使得PID控制参数调整速度较传统方法快,产生超调量较小,该方法的调节效果较好。Based on particle swarm optimization（PSO） and classical PID controlling theory,a PSO-PID controller,using Integral Trisquare of Square Error（ITSE） function as fitness function,was developed.PSO was presented for the optimization of a two-cylinder electro-hydraulic synchronizing system.The simulation shows that PSO makes the tuning of PID control parameters quicker,the overshoot smaller,and this approach has better performance.
