中文摘要：
提出一种基于分批试验结论和考虑工况的球磨机连续磨矿粒级质量平衡模型（PBM）改进模型。基于某些粒级不符合一级磨矿动力学的分批试验结果改进破碎率模型;为消除干扰影响,建立破碎率模型参数和各工况变量间的LSSVM关系模型;基于改进模型,采用PBM＋MPC实现球磨机优化控制。仿真结果表明,PBM＋MPC能有效消除过程干扰,稳定过程产品质量。
英文摘要：
An improved ball mill PBM model considering the conditions for continuous operation was proposed based on the batch-grinding results.The breakage-rate model was improved according to the batch-grinding results that some certain size does not meet first-order grinding kinetic.To eliminate the influence of disturbances,a LSSVM relationship model between the parameters of breakage rate model and the manipulated variables was built.To realize the optimization control of ball mill,a PBM＋MPC scheme was proposed based on the new model.Simulation results show that PBM＋MPC can eliminate the disturbances and stabilize the product quality of the process efficiently.
