以某电厂中速磨煤机为例，依据现场测试数据，采用测试建模方法，给出了中速磨被控对象的数学模型。根据动态矩阵预测控制理论，建立了中速磨煤机动态矩阵控制算法，利用Matlab仿真语言，编制了中速磨煤机动态矩阵控制程序，研究了中速磨被控对象参数变化范围。研究了输出误差加权矩阵、控制量加权矩阵，预测时域长度、控制时域长度，阶跃响应截断时间对控制质量的影响；在所有参数均为最佳的条件下，与常规PID控制进行了对比分析。大量的仿真研究表明，中速磨煤机动态矩阵控制优越于常规的PID控制。

With the on-site parameter from the middle speed mill according to some power plant as an example, the mathemati-cal model of middle speed mill is gived by using the test-modeling method. Depending on dynamic matrix control theory, the algo-rithms of middle speed mill Dynamic Matrix Control is programmed by using Matlab simulation language. The change range of pa-rameter of controlled objects, the output error weighted matrix, the controlling variable weighted matrix, the length of the predicted time-domain, the length of the controlling time-domain and end time of step are studied to controlling quality; Under the optimal conditions of both parameters, dynamic matrix control on middle speed mill is compared to convention PID controlling protocol. A large number of experiments give the conclusion that dynamic matrix control on middle speed mill is better than convention PID controlling protocol.
