27、文以鞍钢弓长岭选矿厂磨矿分级自动控制系统为对象,研究了选矿厂球磨分级自动控制技术,提出了基于模糊控制的多变量系统实施方案。选矿球磨分级过程自动控制的目标在保证产品粒度的前提下,尽可能地提高球磨机处理量,提高磨矿分级生产效率。论文根据此控制目标,在分析弓长岭球磨分级实际情况基础上,提出了磨矿分级现场总线控制系统方案,并针对磨矿过程的工艺特点,把整个磨矿分级控制系统拆分为3个子系统:磨机给矿控制、磨机磨矿浓度控制和分级溢流浓度(粒度)控制,每个子系统实现特定的调节目标。在子系统的基础上实现串级控制和入磨台时的优化控制。由于磨矿分级生产过程是一种多参数、时变的、非线性的、大滞后的生产过程,很难建立精

28、确的数学模型,单纯采用传统的PID控制方案参与磨矿分级的控制,不能实现磨机稳定运行,达不到理想的控制效果。在充分研究磨矿分级过程工艺特点后,子系统中均采用了模糊+PID的控制方案。具体将整个控制过程分为3个主要测控模块即:磨矿能力测控、磨矿浓度测控、分级溢流浓度(粒度)测控。实践证明,该控制方案实现了磨矿分级生产过程的稳定运行,达到了理想的控制效果。既保持PID控制的无静差、稳定性好的特点,模糊控制又兼顾了多因素影响的非线性特点,提高了对参数的适应性,加快了调节速度。同时,磨机给矿量控制子系统在实际运行中,在模糊控制基础上进一步采用“步进式搜索自寻优”办法,实现磨矿分级过程优化控制。上述设计的
