Most industrial semi-autogenous grinding (SAG) mills use heuristic control approaches such as expert systems to achieve stable operations and improved performance. Model-based control techniques have not received successful applications in industrial SAG mills due to complexity of the processes and lack of accurate models. Owing to the need to improve the performance of SAG mills beyond that of the experience-based heuristic control approach, this project proposes to develop high fidelity models for industrial SAG mills and investigate the effect of industrially important variables on their operation. Both fundamental modelling based on first principles and statistical techniques using industrial operating data will be used in model development. Model-based control will be developed and its performance will be investigated using simulations. Results of this project will generate important information for new control implementation as well as existing control improvement with minimal costs for industrial SAG mills.

大多数工业半自磨 (SAG) 磨机使用专家系统等启发式控制方法来实现稳定运行和提高性能。由于过程的复杂性和缺乏准确的模型，基于模型的控制技术尚未在工业半自磨机中得到成功的应用。由于需要提高半自磨机的性能，超越基于经验的启发式控制方法，该项目建议开发工业半自磨机的高保真度模型，并研究工业重要变量对其运行的影响。基于第一原理的基础建模和使用工业操作数据的统计技术都将用于模型开发。将开发基于模型的控制，并通过仿真研究其性能。该项目的结果将为工业半自磨机的新控制实施以及现有控制改进提供重要信息，并以最低的成本。
