Research on and Analysis of PID Controller Parameter Optimization Based on PSO Algorithm

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.
