| Popis: | In order to improve the communication rate of the cyber–physical fusion system, and at the same time guarantee the quality of system demand of each user, a CPS (Cyber–Physical Systems) communication resource allocation algorithm based on cooperative game was first proposed. The resource allocation process of the orthogonal frequency division multiple access network downlink in CPS is modeled as a cooperative game among multiple users, and the Pareto optimality among users is achieved by solving the Nash bargaining solution. Secondly, this paper studies the cooperative task assignment of communication resources for actuators in CPS execution network, and proposes a feasible task assignment method of communication resources based on K–M algorithm. Simulation experiments show that the task allocation result obtained by this method is better than that of auction method, and the algorithm running time can also meet the limit of actual demand. Finally, in consideration of the control center’s need for fine control of the actuator, this paper studies the wireless resource allocation problem between a control center and the actuator, and maximizes the control effect of the actuator as the daily standard, and proposes a dynamic Joint allocation scheme of subchannels and power. Simulation results show that the proposed scheme can maintain a high level of control effect even when the transmission power of the control center is small, which effectively saves the energy consumption of the control center. |
