The invention relates to a process diagnosis system and a method for the diagnosis of processes and states in a technical process, in particular for the diagnosis of a power station process. The invention is a structured multi-agent system which corresponds to the process and has a plurality of autonomous diagnostic agents. The diagnostic agents in each case contain a neural network, with whose aid a reference behavior of process components that are to be monitored can be learned. In addition, automatic adaptation to a new reference behavior is also possible by the diagnostic agents.

[ We claim:] [7.] A method for carrying out a process diagnosis, which comprises:providing a plurality of diagnostic agents to a process control system for monitoring process components of the process control system during a process, the diagnostic agents including lower order diagnostic agents and a higher order diagnostic agent forming a multi-agent system;learning in a first commissioning phase reference behavior of the process components of the process to be monitored by each of the lower order diagnostic agents and storing the reference behavior as intended behavior;determining in an application phase actual behavior of the process components and comparing the actual behavior with the stored intended behavior by each of the lower order diagnostic agents;reporting any detected deviations in a form of deviation reports to the higher order diagnostic agent by each of the lower order diagnostic agents;carrying out a diagnosis in the higher order diagnostic agent on a basis of the deviation reports received from the lower order diagnostic agents and on reference behavior stored by the higher order diagnostic agent; andif no fault is detected, reporting with the higher order diagnostic agent to the lower order diagnostic agents that there is no fault present and that a reference model in at least one of the lower order diagnostic agents is to be adapted; andif a fault is detected by the higher order diagnostic agent, reporting the fault with the higher order diagnostic agent to a superior higher order diagnostic agent thereof or outputting a fault report with a reporting device.
