In recent yc缸s，it is remarkable to see 由e increasing number of studies rcJalcd 10 由e fractiona1 order control tcchnology， 仕actiona1 order proportion a1 integra1 derivative con位ollers are widely used，it has two additiooa1 p缸缸netcrs which can be adjusted，so it can flexibly conlroJ the controlled object and has strongcr robustness and better e1IecL In this pape巳 fractional order PID controllcr is researched dccply. First，a superior Ousta1oup filtcr a1gorithm is achieved ，we can mask the Oustaloup module using mallab/simuJink model，and solve the fractional order differenti a1 equations elTectively based 00 由is module，then we sct up a model for the fractional ordcr PID controLler and 企actiona1 control system，and we veri马， the acc町acy of the model. Second，as 由e fractiona1 order PID controller having five p缸ameters induding integral order and diffcrcntia1 order，it is difficuJt to sct the appropriate parameters ， based on genctic a1gorithm tuning of PID controller paramclers，we preseol methods for luning parameters of 岳actional order PID controLler based on GA and PSO，it can get thc five parameters of the controller direclly. Finally，in order to verify 山e superiority of fractiona1 order PID controller and the effectiveness of the method ，we conducted the simulation research including robustness and antiτjamming of the control systcm ，and the pcrformance of the controller using in the system with time dclay.
