The development of an innovative controller for looper and tension control in hot strip finishing mills is traced based on the combination of H∞ and ISMC (integral sliding mode control)approaches. First, an H∞controller is designed to robustly attenuate the unmatched disturbances in the angle and tension loops. Then, ISMC is used to overcome the matched disturbances in the actuators which guarantees the reliability and performances of the overall system. This solution has been considered thanks to it swell-known robustness and simplicity characteristics concerning disturbances and un modeled dynamics. Simulation results show the effectiveness of the proposed controller compared with conventional ones.
