摘　　要：本文针对PID控制器参数整定的问题,提出了一种基于粒子群优化的PID控制器设计方法。首先建立PID控制器仿真模型,然后将待优化的三个参数(KP、KI和KD)作为粒子群中的粒子,采用误差绝对值时间积分函数ITAE作为优化目标,将PID控制器参数整定问题转化为优化问题,最后将设计好的PID控制器进行仿真实验。仿真结果表明,该方法与传统的整定方法相比,具有更好的动态响应特性和满意的控制效果,进而验证了该方法的可行性和有效性。A design method based on particle swarm optimization was proposed for tuning PID controller parameters. Firstly,the simulation model of PID controller was established,and then the three parameters（ KP、KIand KD） to be optimized were taken as particles on particle swarm,the integrated time and absolute error（ ITAE） was taken as optimization objective,and the problem of tuning PID controller parameters was translated into optimization problem,finally,the designed PID controller was simulated. The simulation results showed that this method has better dynamic response characteristics and satisfactory control effect than traditional tuning method,Furthermore,the feasibility and validity of the method were verified.
