Is Hop-by-Hop Always Better Than Store-Carry-Forward for UAV Network?

IEEE Access (2019)

Fei Xiong Xia Lei Jiejie Xie Hai Wang Aijing Li

As energy supply on Unmanned Aerial Vehicle (UAV) is limited, energy efficient data transmission in UAV networks would be of great concern to the researchers. Nevertheless, UAV networks exhibit strong dynamic nature compared to ordinary Mobile Ad hoc Network (MANET), it is not rare that some nodes will be disjoint from other nodes from time to time. Under such circumstance, ordinary hop-by-hop routing schemes can not be used anymore, for there is no route existed from source to destination. Some solutions use store-carry-forward (SCF) routing to facilitate end to end data transmission. However, when should we use SCF routing, when we should use hop-by-hop routing if we taking energy into consideration? Is hop-by-hop routing always better than SCF? If it is good or not when the hop-by-hop routing is combined with the SCF routing? All these questions need to be answered. In this paper, we answered above questions by proposing three types of minimum energy consumption models of hop-by-hop routing, and two SCF routing models. We compared all these models and considered four tactics of combination modes for the transmissions in a rotary-wing UAV network. The researches show that two tactics have better performance than other modes in energy saving capabilities by reducing 70% at most with the hop-by-hop routing, and the transmission time of combination modes are in same scale compared with hop-by-hop routing. The two tactics are appropriate for different UAV networks respectively, in which the source UAV can or cannot get the GPS information of relay UAVs in the route. The research conclusion can also be used for the transmissions in a fixed-wing UAV network by modifying the energy consumption models of fixed wing UAV, which is different from rotary wing UAVs.

Effect on Hydrogen Risk of Initial Gas Injection Time During AP1000 Post-Inerting

Xuefeng Lyu YanLin Chen Xiaobo Li Shengfei Wang Yu Yu

To calculate the hydrogen risk at severe accident of small break of cold leg in 1# steam generation compartment with ADS4 invalid in AP1000 nuclear power plant, and apply the results to level2 probabilistic safety analysis, we study the effect of initial gas injection time on reducing hydrogen risk during AP1000 post-inerting, the initial gas injection times are 300 second, 500second, 700second, respectively. First, analyzing the total elimination of hydrogen by recombiners. Then, analyzing the average hydrogen mole fraction, flame acceleration factor in 1# steam generation compartment and in upper space of containment. Finally, analyzing the pressure and average temperature in containment. The results show that, the premature injection of inert gas can slow down hydrogen diffusion rate from 1# steam generation compartment to the upper space of containment, which causes hydrogen risk rising in 1# steam generation compartment. Post-inerting can ease hydrogen risk in upper space of containment, but can’t ease hydrogen risk in 1# steam generation compartment effectively. The pressure of containment is only relevant to the total mass of inert gas, and the pressure of containment is always less than limit pressure, so the containment breakage is nearly impossible.

Sampled-data based output tracking H<inf>∞</inf> control for PMSM servo system

Yu Yu Yanjun Shen Yungang Liu

In this paper, a sampled-data based output tracking H _∞ controller is designed for the permanent magnet synchronous motor (PMSM) servo system. Firstly, the stator voltage is used as the control input of the PMSM servo system, and the motor speed is used as the output of this servo system. The mathematical model of PMSM servo system is established. Then, a sampled-data state feedback controller is designed such that the motor speed can track a given reference signal. In order to solve this problem, the sampled-data H _∞ performance index of output tracking is defined. The problem of output tracking is transformed into the problem of sampled-data based H _∞ control problem. Finally, simulation results show the feasibility and effectiveness of this controller design method.
