Control method for fabric winding based on AC torque motor

Based on the control requirement of tension-velocity(T-V) coordination in fabric winding system,this paper raises a practical formula of mechanical characteristic for AC torque motor and a calculation equation of negative taper winding characteristics.On this basis,it analyzes the application scope and performance of AC torque motor′s open-loop winding control,and a semi-closed loop adaptive control method which takes web radius as a variable,and a high-precision closed loop winding control method which is based on intelligent feed-forward and feedback.MatLab simulation results and comparative analysis have showed the advantages of the new control approaches.These methods satisfy the winding control requirements of different production processes and have found practical applications.The paper also introduces technical implementation of two T-V coordination control methods mentioned above.
