Dynamic of a Rewinder with Feedback by Tension Force // Electronics and
Electrical Engineering. Kaunas: Technologija, 2008. No. 1(81) P. 4144.
Processes of rewinding the tight bands of various elastic
materials are very often in various technological lines. The highest process control
quality is achieved only by employing feedback signal of tension force of the
tight band. Therefore in this article there is proposed structure of control
system and strategies for control with direct measurement of tension force in a
rewinder system. The proposed control strategy allows stabilizing the tension
force neglecting the change of diameters of the unwinding and rewinding rolls. The
tension force of the tight band is controlled by using the electromagnetic
friction clutch while the linear speed of coiling is adjusted by frequency
drive. For the proposed system the performance evaluation and adjustment the
equations of nonlinear control system with three closed loops are developed and
modeled by using MATLAB/SIMULINK program package. The results of the
mathematical modeling have shown good coincidence with the real experimental
results. Therefore the mathematical model might be used for determining optimal
PID control parameters of real tide band coiling system. Ill. 6, bibl. 11 (in
