Efficient and flexible information flow mode is an important guarantee for the victory of information war. The current research on battlefield information flow mode is difficult to adapt to the network centric operational concept. The performance analysis of information flow mode is mostly focused on the topological structure characteristics of complex networks, and there is no method to analyze the overall performance of information flow. Aiming at the construction of battlefield information flow mode under information conditions, a general model of battlefield information flow based on complex networks is established, an information flow network of basic campaign scale is generated, and key indicators describing the overall performance of the information flow network are established. Through simulation experiments, analysis and comparison are made, and the overall performance of the information flow mode constructed in this paper has certain performance advantages.

An EMS(ElectroMagnetic Suspension) system is a complex control system, consisting of many interacting subsystems. For control design, there is an obvious trade-off between design complexity and performance, just as there is a trade-off between model complexity and its utility. In this paper, we represent three mathematic models of an EMS system, and demonstrate theoretically that the model based on "half bogie" EMS subsystem captures the dynamics sufficiently to obtain a high performing controller. From a control design point of view, there is no need to model at the full bogie or multiple bogie system level, on the contrary.
