灰色模糊控制在煤泥水自动加药系统中的应用

his paper introduces the present situation of the coal slime dosing system and the objective requirement of realizing automation of dosing system in the development of coal washery.According to the characteristics of system that complex, nonlinear and delay, put forward the grey fuzzy control algorithm.Under the open loop control,and use turbidity sequence of the coal slime water,establish GM (1, 1) forecasting model,use quantitative step length prediction of the model to eliminate system lag.And then error between the system predicted value and setting value is applied in fuzzy controller for adjusting dosage.Through the field experiment data acquisition,the results show that grey forecasting-fuzzy control algorithm can solve the system unknown and big lag problems ,which can make dosing more timely and the operation of the system more stable.
