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.

基于合作博弈的CPS通信资源分配算法

为了提高电子物理融合系统的通信速率,同时保证每个用户的系统需求质量,首先提出了一种基于合作博弈的CPS(网络物理系统)通信资源分配算法。将CPS中正交频分多址网络下行链路的资源分配过程建模为多个用户之间的合作博弈,通过解决纳什讨价还价解决方案实现了用户之间的帕累托最优。其次,研究了CPS执行网络中执行器通信资源的协作任务分配,提出了一种基于KM算法的可行的通信资源任务分配方法。仿真实验表明,该方法获得的任务分配结果优于拍卖方法,算法运行时间也可以满足实际需求的限制。最后,考虑到控制中心需要对执行器进行精细控制,本文研究了控制中心和执行器之间的无线资源分配问题,并以执行器的日常控制为最大标准,提出了一种动态联合方案。子信道和功率分配方案。仿真结果表明,该方案即使在控制中心的发射功率较小时也能保持较高的控制效果,有效地节省了控制中心的能耗。最后,考虑到控制中心需要对执行器进行精细控制,本文研究了控制中心和执行器之间的无线资源分配问题,并以执行器的日常控制为最大标准,提出了一种动态联合方案。子信道和功率分配方案。仿真结果表明,该方案即使在控制中心的发射功率较小时也能保持较高的控制效果,有效地节省了控制中心的能耗。最后,考虑到控制中心需要对执行器进行精细控制,本文研究了控制中心和执行器之间的无线资源分配问题,并以执行器的日常控制为最大标准,提出了一种动态联合方案。子信道和功率分配方案。仿真结果表明,该方案即使在控制中心的发射功率较小时也能保持较高的控制效果,有效地节省了控制中心的能耗。提出了一种动态的子信道和功率联合分配方案。仿真结果表明,该方案即使在控制中心的发射功率较小时也能保持较高的控制效果,有效地节省了控制中心的能耗。提出了一种动态的子信道和功率联合分配方案。仿真结果表明,该方案即使在控制中心的发射功率较小时也能保持较高的控制效果,有效地节省了控制中心的能耗。
