Study on Fuzzy Integral Sliding Mode Control in Hot-strip Mill AGC
Due to the important role that automatic gauge control (AGC) plays in strip steel production, fuzzy sliding control was attempted to be applied into mill AGC system. Moreover, in order to eliminate steady-state errors in system and improve control precision, integral control was also introduced into the sliding mode variable structure control, which means adopting fuzzy integral sliding mode control (FISMC) method to control the roll gap value to its permissive fields, thus eliminating the changeable mill gauge brought by changeable roll gap, consequently, AGC was achieved. Simulation results show that FISMC not only exhibit strong robustness but also avoid the chattering phenomena, showing a promising application future.
