Abstract :
A more accurate useful model of mould level control system is obtained by introducing the colored noise term in the system model. On the basis of this model, a robust generalized predictive control method (CGPC) which can distract the effect of colored noise, such as speed changes or other disturbances, is used in mould level control. The simulation experiments show that the robustness and error of mould level controlled by CGPC are greatly improved than the conventional GPC
