“…The B777 aircraft high lift system has two identical flap slat computers (FSEU1 and FSEU2) [1] and only one FSEU output command at a time. After the post-flight self-test, FSEU1 and FSEU2 automatically switch to the master state.…”

The design of high safety and reliability slat flap control computer (SFCC) has become the main objective of flight control development. Firstly, the design requirements proposed. Secondly, the design of foreign advanced civil aircraft flap slat computers is summarized. Based on one type of aircraft SFCC design, the operation mode, redundancy management, synchronization, and monitoring design of the SFCC are analyzed in detail, and a design scheme of civil aircraft SFCC, which meets the requirements of safety and reliability, is proposed. Based on SFC real-time test environment, the SFCC design logic is verified. Taking the design and test of the flap motor direction error monitoring as an example, the test results show that the scheme design is reasonable and feasible, and the reliability of the flap slat computer is effectively improved.

“…It can be found that when using the time-triggered control strategy, the fixed sampling period is generally chosen to be relatively small to take into account the system stability and performance, which inevitably results in frequent controller updates and data transfer. In the operation process, when the difference between the two sampled state values is small and the system tends to be stable, there is no need for the system to update the controller frequently and pass the information several times [17]. Although the time-triggered control will reduce the number of communications and controller updates to a certain extent, it also causes unnecessary consumption of computational and communication resources.…”

The time-sampling control strategy has communication discontinuities in the control of multiple AUVs (autonomous underwater vehicles). To overcome this problem, a distributed event-triggered communication mechanism is proposed to make each AUV communicate only when its own state is updated, which reduces the frequency of communication and improves the stability. This mechanism has better adaptability for formation control between heterogeneous AUV groups. At the same time, two consistency control algorithms based on event-triggered for homogeneous and heterogeneous AUV groups are studied, respectively. The known consistency algorithms are applied to the control of heterogeneous AUV groups for comparative analysis. The simulation results demonstrate that the number of communication among AUVs under the event-triggered control strategy can be significantly reduced. Therefore, the stability of the system is improved. Compared with the traditional consensus algorithm, the algorithm proposed in this paper has advantages in the control of heterogeneous AUV groups.

“…In the study of Lin et al [ 13 ], a practical collaboration infrastructure for 5G network slice broker is designed, where the core challenge is the consensus protocol to guarantee the security and performance of the overall system. By solving the consensus problem, many related applications can be realized, such as the adaptive weighted replication [ 14 , 15 ], information retrieval [ 16 , 17 ], and the flight control system [ 18 , 19 ]. In addition, the consensus problem has also been studied and widely used in various fields such as blockchain and IoT [ 20 , 21 ].…”

The continuous development of fifth-generation (5G) networks is the main driving force for the growth of Internet of Things (IoT) applications. It is expected that the 5G network will greatly expand the applications of the IoT, thereby promoting the operation of cellular networks, the security and network challenges of the IoT, and pushing the future of the Internet to the edge. Because the IoT can make anything in anyplace be connected together at any time, it can provide ubiquitous services. With the establishment and use of 5G wireless networks, the cellular IoT (CIoT) will be developed and applied. In order to provide more reliable CIoT applications, a reliable network topology is very important. Reaching a consensus is one of the most important issues in providing a highly reliable CIoT design. Therefore, it is necessary to reach a consensus so that even if some components in the system is abnormal, the application in the system can still execute correctly in CIoT. In this study, a protocol of consensus is discussed in CIoT with dual abnormality mode that combines dormant abnormality and malicious abnormality. The protocol proposed in this research not only allows all normal components in CIoT to reach a consensus with the minimum times of data exchange, but also allows the maximum number of dormant and malicious abnormal components in CIoT. In the meantime, the protocol can make all normal components in CIoT satisfy the constraints of reaching consensus: Termination, Agreement, and Integrity.
