PSO算法是计算智能领域,除蚁群算法、鱼群算法之外的一种群体智能优化算法。本文研究了PID控制器优化设计的性能指标的选择问题,介绍了PSO算法的基本原理,给出了利用其进行PID控制器参数优化设计的步骤,并给出仿真实例;通过与GA算法、一些改进的PSO算法仿真结果作对比,得出PSO仍可继续应用于PID控制器参数优化当中。
PSO algorithm is a kind of swarm intelligence optimization algorithm except ant swarm algorithm and fish swarm algorithm in computation intelligence field. This paper studies the choice problem in performance index of PID controller optimization design,introduces the basic principle of PSO algorithm,gives the steps for PID controller parameter optimization design by using the principle,presents simulation examples,and draws the conclusion that PSO may continue to be applied to PID controller parameter optimization by comparing the simulation results between GA algorithm and some improved PSO algorithms.
