Research on Fuzzy decoupling control of multiple parameters of dense medium separation of coal

The paper mainly analyzed the control and decoupling processes of two important parameters density and level of suspension,which have the decupling effect.The method introduce a fuzzy decoupling,and using two separated fuzzy controller as decupling compensator,and then combined with PIC controller to control density and level of suspension.The emulation analysis result shows that this method is simple and effective and achieved the expected result.
