Embodiment Construction
[0033] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
[0034] Such as figure 1 and 2 As shown, a raw foil machine winding tension control system includes a winding device 100 for winding raw foil and measuring the actual winding tension and actual winding speed, and a controller, the controller includes:
[0035] Tension comparison unit 200, which is used to calculate the difference between the actual winding tension and the tension preset value to obtain the tension difference;
[0036] A parameter update unit 300, which calculates a tension adjustment parameter and a speed adjustment parameter according to the tension difference;
[0037] A tension control unit 400, which adjusts parameters according to the tension difference and the tension and calculates the speed reference value of the winding device;
[0038] A speed comparison unit 500, which is used to calculate the difference between t...
