cts of DeadTime and Parameter Variations”,IEEE ,,October 1993.The Design and Research of Two Degree of Freedom PID Control SystemSunWei(School of Physics and Electrical of Anqing Normal College, Anqing 246011) Abstract: The traditional PID controlis adegree of freedom PIDcontrol,acontrol parameter of the systemcan only beset,so it is very difficultin the practical controlto getideal control effect.And the twodegree of freedom PID control system can beindependently settwo control parameters,the systemset point trackingeffect andsuppress the interferenceeffect and at the same time paperintroducesthetwo degree of freedom PIDcontrol method.Secondly,according to the transfer functionof thecontrolled objectselected in advanceof the controlled systemis analyzed,and the controlparameterssetting.Thirdly,based on the parisonofseveral control methodsof thecontrol effect,make thetwo degree of freedom PIDcontrol mode selection.Finally,throughMatlab simulation software,and analyzes the results. Key Words: Two degree of freedom PID control, set point tracking, disturbance rejection
