Abstract:

A cyber-physical systems architecture model (CPSAM) is set up based on Object-Oriented Petri nets from the point of view of multi-agent systems, which is composed of sensor node agents, actuator agents, and controller agents. The CPSAM can accurately and unambiguously model the overall and individual characteristics, as well as static and dynamic semantics of CPS. Moreover, the CPSAM can be simulated, analyzed and verified by the well-established analysis methods and supporting tools of Petri nets. Consequently, the defects in the early design stage can be detected, and the correctness and reliability can be improved. The modeling, analysis and design of the target tracking systems demonstrate that the CPSAM can effectively design and develop CPS.

Key words: cyber-physical systems, multi-agent systems, Petri nets, analysis
