摘要
针对某锡石-多金属硫化矿两段磨矿回路中大时滞问题提出了一种主控回路和副控回路相结合的史密斯(Smith)预估控制方案,可以很好的降低分级磨矿系统中由于时间延迟对给矿量和给矿水量的不利影响,缩短响应时间,改善分级磨矿系统的调节品质。MATLAB仿真结果表明,Smith预估控制方案在被控对象模型不精确的情况下对大时滞对象的控制,具有较好的适应性,可以取得较好的控制效果。
A Smith predictive control project based on combining main control circuits and side control circuits is proposed for a cassiterite polymetallic sulfide ore having two-stage grinding circuit with large time delay.This method can reduce time delay in the grinding classification system which has adverse effect to ore feeding rate and ore feeding water,shortens the response time and improves the control quality of grinding classification system.MATLAB simulation result indicates that this method can control large time delay without imprecise plant model,which exhibits preferable adaptability and can obtain better control effect.
