Study of heavy medium coal preparation process control model and control algorithm

Taking the heavy medium three product cyclone coal preparation as the example, and based on the dynamic variation relationship between various technical parameters in the work process, a mathematic model of heavy medium coal preparation process control system that is suitable for different heavy medium coal preparation process is developed. The system performance is analyzed, and a plan of designing heavy medium coal preparation process control system with the application of self tuning control principle is put forward, its control algorithm is given and the computer system simulation on different control algorithms is introduced. The results prove that the self tuning control system is feasible and the effect is superior to the presently used PID control system.
