Abstract.
Because there are exothermic and endothermic phenomenon in the reaction process and the variation of raw material purity, type and amount of catalyst, temperature and flow of circulating water and hot-water, the reactor is difficult to meet the industrial needs by classical control scheme.
M is control time domain, N is model length, P is optimization time domain.[5] (8) (9) (10) Predictive Model With System Uncertainty If consider the influence of the variation of raw material purity, type and amount of catalyst, temperature and flow of circulating water and hot-water, the predictive model with system uncertainty can be obtain as (11) = (12) (13) Feedback Compensation Because the reactor temperature control system has various disturbances, so the predictive model should be
