一、引言在水泥生产过程中,生料配置是重要的工程之一。配料质量的好坏直接影响熟料和水泥的质量以及窑磨主机运转的操作条件和经济指标。目前我国有不少的小水泥厂生料配置仍处于圆盘喂料、人工分析生料成份和人工控制配比的落后状态,合格率很低。稍先进的一些单位则采用PID调节器为基础的自动控制生料的配比方法。由于生料配置系统是一种具有较大纯滞后、其参数也存在缓慢变化的系统,加上生产现场存在较大的随机干扰(球磨机等),因此用定常系统所用的反馈控制方法来整定PID参数就比较困难(有时不能得到满意的效果)有鉴于此,我们设计了小水泥厂生料配置的自校正控制系 I. Introduction In the cement production process, raw material allocation is one of the important projects. The quality of the ingredients directly affects the quality of clinker and cement as well as the operating conditions and economic indicators of the operation of the kiln mill. At present, there are many small cement plants in our country raw material configuration is still in the disc feeding, manual analysis of raw materials and manual control ratio of the backward state, with a low pass rate. Some of the more advanced units use PID regulators as the basis for the automatic control of raw material ratio method. Because the raw material configuration system is a kind of system with large time delay and its parameter changes slowly, and there is large random disturbance (such as ball mill) in the production site, the feedback control method used in the steady system is used to set the PID Parameter is more difficult (sometimes can not get satisfactory results) In view of this, we have designed a small cement plant raw material configuration self-tuning control system
