Sliding Mode Control(SMC) as a Variable Structure System(VSS) and a nonlinear control theory, has been widely used in various engineering fields, and carried out excellent performances in practical use. The purpose of this study is to make a try of utilizing SMC for hot strip finishing mill. The plant is described as a MIMO system and The influence of thickness measurement dead-time is canceled with the use of an augmented VSS observer. A state predictor is also used to compensate the time delay caused in calculation and transmission of process computers. A new approach of discrete SMC which can remove the chattering phenomenon entirely, is proposed with the use of linear reaching function. The usefulness and robustness of the SMC are demonstrated through computer simulations under plant perturbation and external disturbances, and compared with a conventional optimal controller. |
