针对构建可信、可控、可扩展的CPS体系结构的内涵要求,提出一种基于改进的无尺度网络的CPS体系构建方法。本方法通过引入节点度的控制,抑制了无尺度网络“富者越富”的现象,并结合CPS体系特点,构建了一种新型的CPS体系结构。仿真结果表明,本文构建的CPS体系结构在面对随机性失效和选择性失效事故时,都拥有较高的连通性,证实了本文所提出的CPS体系构建方法,在一定程度上提高系统的稳建性。
Aimed at the connotation of building trusted, controllable and extensible CPS architecture, a new CPS architecture based on improved scale-free network is proposed. By introducing the control of node degree, this method suppresses the phenomena of scale-less network and “richer people and richerness”, and constructs a new type of CPS architecture based on the characteristics of CPS. The simulation results show that the CPS architecture constructed in this paper has high connectivity in the face of stochastic failure and selective failure, which proves that the proposed CPS architecture proposed in this paper can improve the stability of the system to a certain extent Constructive.
