Intelligent Control and Optimization of the Coal Slime Flotation
Advanced Materials Research, 2012The inchoate algorithm for the coal slime flotation control is the feed-forward control to the feed concentration and the reagent quantity. This control model is widely utilized because of the easy realization once the used sensors are reliable. However the control results are usually not so good as it cannot adapt the quality fluctuation of the feed ...
