Abstract
In this paper, we propose a control technology to prevent and reduce the center position error in the annealing and pickling process. A coupling control is developed to solve the problem of independent control using individual sensors. We design a receding horizon controller (RHC) to reduce the error and consider the limiting conditions of control input and state variables based on actual data. We also design a filtered predictive PI (FPPI) controller structure to reduce the measurement delay problem, disturbance and modeling error at high frequencies. The simulation results demonstrate the successful performance of the command following and the disturbance reduction by the proposed control scheme.
