浮选柱多输入/多输出控制系统设计及应用
Journal Title: Science Paper Online - Year 2009, Vol 4, Issue 11
Abstract
分析和阐述了浮选柱监控系统的控制要求和原理，采用多变量输入/多变量输出的设计思路，选用开物2000工业组态软件和PLC作为开发工具。通过球形浮子-超声波探测器测定浮选柱液位的高度，采用在线自调整参数的模糊控制、PID控制和充气量控制相结合的控制方法，控制浮选柱液位高度和产品质量；用金属转子流量计检测空气流量，并根据液位变化对充气量实行串级控制。通过对影响浮选效果的重要参数和泡沫状况实施监控，实现了浮选柱生产过程的稳定控制，从而保证了产品质量。在湘安钨矿的应用结果表明，浮选柱控制系统运行状况良好，精矿产品质量的稳定，达到了预期的目标。
