ball mill coal control power plant

Abstract: 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.
