Abstract
In dense-medium separation, the density control is the key to guarantee for product quality. The relationship between the density and liquid level is coupling. This paper investigates the dynamic properties of media density and liquid level in dense-medium separation, proposes to use variable separation method of fuzzy control, designs the fuzzy controller for density and liquid level, and then makes simulation analysis through the simulation. The results show that, density control can meet the accuracy requirements, the time of regulation for liquid level is longer than the time of regulation for density, but there is no overshoot in liquid level regulation which is close to actual experiences. The system can suppress the interference effectively which meets the requirements of media control in dense-medium separation.
