Dynamic Characteristics and Double Closed Loop Control Method of Warping Machine

Abstract:

The warp tension is caused by the speed difference between rewinding shaft and unwinding shaft. The mathematical dynamic models of the system are established based on rewinding shaft and unwinding shaft．Double closed loop are included in the control system. One is winding speed closed loop which could control warping speed according to the requirements; the other is tension closed loop which ensure the yarn tension to be kept constant. The experimental results show the curve of tension enters a stable state after two or three times’ oscillation. The accuracy of the yarn tension has reached ±3%.
