| Abstract: | Based on analysis of the influence of different channels with different degrees of nonlinearity on the layer switching, and model switching between the layers on the dynamic performances, a model switching method is proposed. The simulation results of a pH neutralization process demonstrate that the multi-hierarchical model predictive control using the new model switching method can improve the dynamic performances with large setpoint change. |
