【Abstract】 To aim at the characteristics of non-linear,long-time delay and multi-agitation on control system for ratio of hydrogen to nitrogen,we take the predictive fuzzy control method,According to the change of parameters and the history record correct the control strategy,researching a general method to control lagging system from a new angle.The practive result in a small nitrogenous fertilizer plant is better.更多还原
