Abstract :
In this paper, the development of an innovative DMPC (Discrete Model Predictive Control) controller for looper and tension control in hot strip finishing mills is traced based on the discretized linear model. First, the nonlinear system is approximately linearized and discretized about the output references of the system. Then, a DMPC controller is proposed to improve the performances of the overall system. Simulation results show the effectiveness of the proposed controller compared with conventional ones.
