1 引言磨机是水泥厂的主机之一,其能耗大,效率低。据有关文献介绍,水泥生产中约有70%的能耗用于粉磨作业,而用于粉磨功(有用功)的能耗仅占磨机耗电量的2%～10%,其余为损耗。因此,合理使用磨机与控制磨机负荷并使之在最佳工作状态下运转,是提高磨机粉磨效率和降低能耗的重要途径。粉磨系统具有非线性、大滞后和慢时变参数等特性,其最佳负荷即最大生产能力随着生产过程中原料的粒度分布,易磨性及研磨体研
1 Introduction Mill is one of the main cement plant, its energy consumption, low efficiency. According to the relevant literature, about 70% of energy consumption in cement production is used for grinding work, while the energy used for grinding work (useful work) accounts for only 2% -10% of the power consumption of the mill, and the rest is loss. Therefore, the rational use of the mill and control the mill load and make it work in the best working conditions, is to improve mill grinding efficiency and reduce energy consumption is an important way. The grinding system has such characteristics as non-linearity, large hysteresis and slow time-varying parameters, and its optimum load is the maximum production capacity. With the particle size distribution, easy grinding and grinding of the raw materials in the production process,
