Research on recognition of working condition for calciner and grate cooler based on expert system

The calciner link and grate cooler link in the cement production have the characteristics of strong nonlinearity, time-varying, large time delay and coupling among variables which cause the big fluctuation of working condition, increasing difficulty of modeling and control. To solve such problem, we propose the working condition identification method based on expert system. In this paper, according to real-time and accuracy control requirements and the site operation experience, we summarize the working condition identification expert rules for calciner and grate cooler links. Then according to the different features of different working conditions, we take different identification methods to recognize working conditions. Based on the above expert knowledge, working condition recognition system can identify the current condition accurately and give reasonable operation suggestions. Condition recognition software is compiled by VB6.0, and field application shows that the project is reasonable and practical.
