Evaporation process outlet solution concentration estimation method based on multi-working-condition information fusion

According to the evaporation process outlet solution concentration estimation method based on multi-working-condition information fusion, an analysis unit, a dimension reduction unit, a clustering unit, a balance unit and a modeling unit in a PC are adopted as application software for estimation, and the evaporation process outlet solution concentration estimation method comprises five steps. On the basis of mechanism modeling, the prediction result is used for complementing the actual concentration of the off-line test, the problem of unbalanced data volume between input and output is solved, and the accuracy of a data-driven estimation model is improved; powerful technical support is provided for ensuring real-time control of key variables in the industrial process, product quality improvement, energy consumption optimization and the like; and a good solution is provided for the similar industrial process estimation problem with the characteristics of high data missing acquisition difficulty, high related v
