The speed tracking control for the high-speed winding system

A kind of feedforward cascade speed tracking control method is put forward to solve the problem of excessive fluctuations of tension which is caused by the speed mismatching between the receiving line and the releasing line when winding at high speed. After analyzing the mechanical structure of the layer winder and the relationship between the speed of floating roller and fluctuations of tension, the conclusion that the essence of the tension control is speed tracking control is summed up. This kind of feedforward cascade speed tracking control method has indirect tension control method by controlling the position of the floating roller as its base, make the rotating speed of the electric motor which releases line closed-loop controlled, and tune the parameters of PID controller to realize that the speed of the releasing line tracks the speed of the receiving line. The experimental results show that the speed of the releasing line can track fast and the tracking time is less than 0.32 (s) when the speed of receiving line has step changes at high speed. So this method can have a good control effect on tension control.
