Research on Fault Diagnosis of Chemical Processes Based on MAS( Ⅱ )

For solving the fault diagnosis problem of chemical processes,a new kind of distributed(cooperative) fault diagnosis model based on multi-agent system is provided.As an example of how to apply this architecture to distributed process fault diagnosis system,an actual system is shown: a fault diagnosis system of urea evaporation and pelleting process.Compared with the centralized fault diagnosis method,the distributed architecture is superior both at communication requirement and computational complexity.
