Multi agent-based DCS with fault diagnosis

The multi agent-based DCS (MADCS) with fault diagnosis function is proposed for the purpose of enhancing both system´s flexibility and reliability. Through cooperation among agents, MADCS can diagnose its own state and attempt to recover itself. Commonly, these agents are driven by time or by event, and do not have the same structure. At the same time, the general structure of agent implementation was shown in this paper. To achieve better performance of the fault diagnosis, two models (serial model and parallel model) of data fusion based on multi-sensor are discussed and used in the MADCS.
