Predictive control based on wiener model for inlet pressure of primary dynamic wave in Sulfuric Acid production from smelter gas

The structural features and parameter identification of wiener model are firstly introduced in this paper, and then through the online solving method Newton-Rapshon, the GPC algorithm based on wiener model is applied to the primary dynamic wave inlet pressure control of Sulfuric Acid Industry. Simulation results show that the GPC algorithm based on wiener model can solve the inlet pressure control problem of primary dynamic wave very well. Considering the inlet pressure drastic change when the working condition switches, some methods are adopted and the control effect is improved fatherly.
