Optimal control for continuous bauxite grinding .Traduire cette page

    Considering the reduction of power consumption of ball-mill,we propose a multi-objective multi-model predictive control for the continuous grinding process of bauxite with bauxite ores coming from different mine sources and with different qualities.In this method,we first build the state-space concentration-predictive model and the finenessprediction model based on the weighted multi-model of ...
