Study on predictive control algorithm for horizon control

In this paper, the predictive control algorithm for horizon control has been studied. The affect of the setpoints obtained with different method for horizon control to the control performance is simulated to the atmosphere distillation column. Based on it, taking advantage of dealing with constraint, the predictive control algorithm is improved by adding the constraint to the control performance. The simulation results show that the control effect has been improved using the improved predictive control algorithm, the robustness is also enhanced.
