【Abstract】 This paper describes an expert control strategy to solve two key problems in the control of the coal blending process, which are to accurately determine the target percentage of each type of coal to be blended, and to track them. First, neural networks, mathematical models and rule models are constructed based on statistical data and empirical knowledge. Then, an expert reasoning method combining the neural network, mathematical models and rule models is proposed for determining the target percentages. Finally, a distributed PI control scheme is used for tracking the target percentages. The proposed strategy is implemented by an expert controller and a distributed controller. The results of actual runs show the validity of the strategy.更多还原
