摘要/Abstract

摘要： Abstract: The development of an innovative H∞ controller for
looper and tension control in hot strip finishing mills is traced based on
approximately linearized model. This solution has been considered thanks to
its well-known robustness and simplicity characteristics concerning
disturbances' attenuation. The controller is designed based on an
optimal problem with linear matrix inequality (LMI) constraints, and the problem is
solved by the mincx function of Matlab LMI Toolbox. Simulation results show
the effectiveness of the proposed controller compared with conventional
ones.
