description: 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.
