Document Type and Number:
Japanese Patent JP7199111
Kind Code:
B2
Abstract:
The invention discloses a rare earth extraction process prediction control method and system. The method comprises the steps: building a rare earth extraction space model by taking the flow of an extraction agent, feed liquid and acid liquor in the rare earth extraction process as the input, taking the concentrations in a water phase and an organic phase as the state, and taking the contents of rare earth element components difficult to extract and easy to extract as the output; discretizing the rare earth extraction output space model to obtain a state space increment model; constructing a predictive control output model based on the state space incremental model; constructing an optimization description problem based on the predictive control output model; solving the optimization description problem to obtain an optimal solution; and determining a control quantity based on the optimal solution, and controlling the rare earth extraction process. The model prediction control MPC method is adopted to process the state space increment model, and the MPC has low requirements on the model and is suitable for multivariable objects, so that the production efficiency and accuracy of the rare earth extraction process can be improved, and the problems of high resource consumption and unstable product quality can be solved.
