【Abstract】 In the production process of phosphoric acid,some key quality indicators cannot be directly measured,which may have adverse effects on the production process and product quality. The article introduces an ensemble learning algorithm and develops a machine learning soft sensing technology method based on gradient lifting decision tree to deal with strong nonlinearity and dynamics in the production process of phosphoric acid reaction tanks.The effectiveness of the improved modeling method was verified through the benchmark of the wet process phosphoric acid reaction tank device. Then,it is applied to practical cases of phosphorus chemical production,indicating that this method is particularly suitable for modeling phosphorus chemical production processes.更多还原
