Control of air-dense medium density based on fuzzy control

The air dense medium fluidized bed concentration is a new method in the separation field. It is widely used because of its vast scope of application. The key part of the air dense medium fluidized bed concentration is the selection of the dense medium. The density of the fluidized bed varies in the separation process. This influences the separation effect. This paper firstly introduces the principal and importance of the density of the dense medium in the producing process of preparation plant, secondly, a fuzzy controller is designed with the density of the dense medium as the control target. At last, the study is done on the basis of different inference methods.
