Optimization control of coal-blending process based on the on-line detection of coal quality

Optimization control method of coal-blending process based on the on-line detection of coal quality were put forward. The mathematic model of stable optimization was established, and design method of cascade control system of coal blending process based on coal quantity regulation was put forward, its performance, probability and necessity of fuzzy control method applying in coal blending process were also analyzed. Combining regular PID control methods, the main-auxiliary feedback self-organizing fuzzy PID controller was designed and the simulation verifies its advantage and stability. The results of practical application show that the performance of the control system is very steady, the effect of control is very obvious and the quality is very stable. The rate of eligibility of blending coal for the new strategy is more 20% than that of handwork.
