【Abstract】 AbstractThis paper discussed the inference control mechanism of monitoring and diagnostic expert system for circulating fluidized combustion boiler on the basis of the references1, 2 and 3. This mechanism is the effective combination of the data driven forward inference chain with the target driven backward inference chain. The five advanced diagnostic techniques, such as candidate generation, discrepancy detection, local diagnosis, constraint suspension diagnosis and constraint propagation diagnosis are included. The principle of fault determination proposed in this paper is relevant for the thermal power system with feedback loops.更多还原
