Optimal for ball mill pulverizing system and its applications
A ball mill pulverizing system is a typical strongly coupled multi-input multi-output (MIMO) plant, which is also nonlinear and widely used in coal-fired power plants. A conventional PID control strategy is not effective for its regulation, so it becomes a difficult problem in thermo-power automation. In view of the key problems in the automatic control of a ball …
