Abstract: Cyber-physical systems (CPSs) are complex systems with high integration and interaction of both computing units and physical objects under the network environment. Complex cause-effect logic relations exist among subsystems of CPSs. In this paper, the problem on modeling CPSs is studied based on a cause-effect logic relation, whereas the model of CPS subsystems is analyzed by applying the control theory and with data processing technologies. The research focuses on the process of dynamic and complex information processing for the insecure environment. The organic integration and the deep cooperation of CPSs are realized by dynamically organizing and managing CPS's inherent foundation. Finally, a simulation on cyber-physical power systems is carried out to assess the effectiveness of the proposed model on CPSs based on the cause-effect logic relation.
