### Optimum strip tension control system for rolling mills

Optimum strip tension control system for rolling mills Abstract A system and method for achieving an optimum interstand strip tension providing substantially equal loading of adjacent stands of a tandem rolling mill where such optimum tension is determined by the expression

### Unified gauge

In this paper the unified gauge-tension control problem is formulated by defining the exit strip thickness of stands and interstand tensions as controlled outputs It is shown that cold rolling process can be described by a nominal model perturbed by an additive uncertainty This model is used to design a robust tracking controller based on H∞ control theory to ensure robust
