%X For the problem of feedback control of flatness in
a cold tandem rolling this paper proposes control techniques
based on quadratic optimization. Three different strategies
are proposed and compared: a centralized solution based on
a global QP problem that decides the commands to all the
actuators, and two decentralized solutions where each actuator command is optimized locally. All schemes are based on a global exchange of information about the commands generated at the previous time step at each stand, required by a synchronizing device that compensates for the numerous delays present in the mill.
