Simple Adaptive Control for Constant Tension of Double Stand Revere Cold-Rolling Mill

A simple adaptive control system was designed for constant tension of double stand revere cold rolling mill. This system contains two inner loops for current and velocity control using PI regulators; its outer loop is for tension control using simple adaptive controller. Simulation results indicate that the simple adaptive controller has better performances than classical PID control method. The system has stronger robustness for constant force control, and improves the precision about the thickness and shapes of steel straps.
