Abstract
Directing against working property and control requirements of the ball mills in thermal power plants
a double-layer control strategy combined self-optimizing control with fuzzy self-adapting sampling PI control has been put forward
realizing load optimization and real-time control of ball mills. The developed load control system of ball mills utilizes ball mill’s load detector based on information-fusing technology of multiple sensors to realize accurate load measurement and adopts a small-size distributed control system (DCS) consisted of a programmable logic controller (PLC) and an industrial control computer. practical application shows that the control performance of above-mentioned control system is good
