A Fuzzy Control Method for Ball Mill System based on Fill Level Soft Sensor
Aiming at the disadvantage of ball mill system control, a new control algorithm based on fuzzy logic control proposed. Firstly, the dynamic characteristic of ball mill pulverizing is given. Secondly, the control method is introduced. For mill level control loop, by the fuzzy decision making, the mill fill level is represented by the out temperature and the differential pressure. Combined with the vibration signal of ball mill bearing, the ultimate set value of ball mill fill level is more rational and accurate. For outlet temperature and inlet negative pressure coupling loop, a fuzzy decoupling control based on the manual operation experience is proposed. Finally, the simulation of the proposed control algorithm is researched. The simulation results demonstrate the validity and practicability of the control method proposed in this paper.
