Density control method for dense-medium suspension based on fuzzy control

In view of problems of poor accuracy and universality of existing density fuzzy control methods for dense-medium suspension, a density control method for dense-medium suspension based on fuzzy control was proposed. The method takes suspension density deviation, variation rate of the suspension densi...

description In view of problems of poor accuracy and universality of existing density fuzzy control methods for dense-medium suspension, a density control method for dense-medium suspension based on fuzzy control was proposed. The method takes suspension density deviation, variation rate of the suspension density deviation and liquid level of qualified medium bucket as input variables of density fuzzy controller, and takes liquid level deviation of qualified medium bucket and variation rate of the liquid level deviation of qualified medium bucket as input variables of liquid level fuzzy controller. Water supply valve and flow-spitting box are effectively controlled by use of the density fuzzy controller and liquid level fuzzy controller, so as to achieve accurate and stable control of dense-medium suspension density. The application results show that suspension density fluctuation range can be controlled at ±0.007 g/cm3 with fast response speed.
