Abstract

This paper introduces a control scheme for the load in the grinding process of the cement raw mill against its characters of nonlinearity and large time delay. An expert control decision is proposed for the control of the grinding process of the cement raw mill. According to the relationship curves between mill load and the three parameters including mill sound, the back powder of the separator, the power load of the bucket elevator, and the expert knowledge bases which are got through further studying the concrete implementation method and technology for the transformation and expression from hidden knowledge to explicit knowledge, we established expert parameter setting incomplete differential PID controller to self-adapt to the operation conditions of three stages: "empty mill", "normal" and "blocked mill". The control system is with strong practicability, strong ability of antiinterference and good robustness, and its efficiency is improved greatly. Through further study of cement grinding process sampling period, expert variable cycle PID control strategy is put forward, and results show that response time is faster and the efficiency is further improved. The intelligent expert control system effective practice and simulation results are confirmed.
