【摘要】 研究了重介选煤工艺介质密度和液位系统的动态特性,液位和密度的多变量模糊控制方法.该方法采用2个独立的模糊控制器,分别控制液位和密度.模拟结果表明这种控制方法规则设计简单、控制效果好.该方法在主再洗工艺的低密度介质循环系统控制中进行了试验,结果表明能满足重介选煤介质循环系统的控制要求.

【Abstract】 The dynamic properties of density and level system of heavy medium suspension in heavy media coal processing are analyzed, and the multivariable fuzzy control system of level and density is studied. This control system consists of two independent fuzzy controllers which are responsible to adjust level and density of suspension in the mixing tank. Simulation shows that this method is simple in designing rule and efficient in heavy medium circulation control. The experimental results, tested in low density suspension circulation control of main separating and re-separating process in heavy media coal processing, show that this control system can meet the need of suspension circulation control.
