This paper presents an expert control strategy which solves the two crucial problems of accurately determining and tracking the target ratio of each kind of coal in process control of coal blending.Firstly, neural networks, mathematical models and rule models are established based on statistical data and empirical knowledge. Then a kind of expert reasoning method is proposed to determine the target ratio, which combines neural network, mathematical model and rule model.Finally, a distributed PI control scheme is used to track the target ratio.The expert control strategy consists of an expert Controller and a distributed controller to achieve the actual results show the effectiveness of this strategy
