摘　　要：为了优化烧结型滚抛磨块的制备,提升磨块的品质,在分析滚抛磨块烧结过程特点和非最小状态空间模型预测控制(NMSSMPC)在乙烯裂解炉的应用基础上,提出了基于卡尔曼滤波的非最小状态空间模型预测控制(KF-NMSSMPC)的方法,将其应用于滚磨烧结炉中。该控制算法通过在模型预测控制(MPC)中加入滤波器来消除烧结过程中的量测噪声和信道噪声带来的影响。KF-NMSSMPC能够有效地适应这样的工业条件,同时还能节能降耗。大量仿真实验结果表明,在模仿实际工业条件下,KF-NMSSMPC比NMSSMPC能有效抑制干扰,快速地跟踪烧结轨迹,降低误差,提高烧结控制过程精度,进而改善滚抛磨块烧结质量。In order to optimize the preparation of sintered tumbling blocks and improve the quality of the blocks, on the basis of the analysis of the sintering process characteristics of tumbling mill blocks and the application of non-minimum state space model prediction(NMSSMPC) in ethylene cracking furnace, a Kalman filter-based non-minimum state space model prediction control(KF-NMSSMPC) method was propased and applied to the tumbling mill sintering furnace. The control algorithm eliminates the effects of measurement noise and channel noise during sintering by adding filters to the Model Predictive Control(MPC). Numerous simulation results show that different from NMSSMPC system, KF-NMSSMPC can effectively suppress disturbances, quickly track sintering trajectories, reduce errors, and improve sintering control process accuracy under the imitation of actual industrial conditions. KF-NMSSMPC can improve the sintering temperature control accuracy of the rolling sintering furnace, which in turn improves the sintering quality of the rolling grinding block.
