给矿PID控制回路和负荷模糊控制组成闭环串级控制系统,内环采用PID调节实现恒定给矿控制,号筒传感器进行磨音检测,磨音频谱分析后反馈给外环模糊控制器,综合实现给矿自动控制,达到给矿量与球磨机实际运行情况的匹配。并将PROFIBUS现场总线技术、PLC、组态软件等成功应用于选矿现场,有利于选矿厂综合自动化的进一步实现。
The PID control loop and the load fuzzy control form a closed-loop cascade control system. The inner loop adopts PID control to achieve constant feed control. The horn sensor performs the grinding sound detection and the audio frequency spectrum analysis and feedback to the outer loop fuzzy controller. Mine automatic control, to the amount of ore to the ball mill and the actual operation of the match. And PROFIBUS fieldbus technology, PLC, configuration software successfully applied to the dressing site, is conducive to the further realization of the integrated automation plant.
