Temperature controller based on self-turning PID for texturing machine

In allusion to such problems of texturing machine temperature control system as large numbers of control channel,high precision demand,complex influencing factor etc.,a temperature control method based on self-turning PID for texturing machine was put forward after making an extensive investigation of the available methods used for temperature control.The trait of texturing machine heating chest was presented;the present temperature control methods were expounded along with the existing problems and the superiority of self-turning PID control was emphasized.Discrete mathematics model was established by the way of the thermodynamics formula,and its model parameters′ recognition was discussed.The design method of pole placement controller was described and implementation scheme for texturing machine was given.Commercial trials have proved that this temperature control system is satisfactory,and can reach the required control precision.
