In this paper, we propose a hybrid multi.system-on-chip (H-MSoC) architecture that provides a high-flexibility system in a rapid development time. The H-MSoC approach provides a flexible system-on-chip (SoC) architecture that is easy to configure for physical- and application-layer development. The physical- and application-layer aspects are dynamically designed and modified; hence, it is important to consider a design methodology that supports rapid SoC development. Physical layer development refers to intellectual property cores or other modular hardware (HW) development, while application layer development refers to user interface or application software (SW) development. H-MSoC is built from multi-SoC architectures in which each SoC is localized and specified based on its development focus, either physical or application (hybrid). Physical HW development SoC is referred to as physical-SoC (Phy-SoC) and application SW development SoC is referred to as application-SoC (App-SoC). Phy-SoC and App-SoC are connected to each other via Ethernet. Ethernet was chosen because of its flexibility, high speed, and easy configuration. For prototyping, we used a LEON3 SoC as the Phy-SoC and a ZYNQ-7000 SoC as the App-SoC. The proposed design was proven in real-time tests and achieved good performance.

최근 IoT 환경에서 많은 디바이스들의 등장과 더불어 특정 사용자만 접근 가능한 보호된 네트워크가 필요하게 되었다. IoT 네트워크 환경에 OAuth 프로토콜을 적용하여 인증하게 되면 보다 쉽게 네트워크 인증 체계를 구축할 수 있으나 OAuth는 공격자가 Token을 가로채게 되면 쉽게 공격에 노출되는 단점이 있어 2차 인증이 필수적이라고 할 수 있다. 궁극적인 IoT는 Fog Computing이 필수적이다. Fog Computing은 Cloud를 확장시켜 network Core에서 뿐만 아니라 Edge에서도 Computing이 가능하게 하고, node간의 통신을 가능하게 하는 플랫폼이다. Fog Computing의 장점으로는 Location awareness나 Support for mobility 등을 들 수 있다. Fog Computing내에서 사용할 인증이 이런 Fog Computing의 장점을 살린다면, 더 IoT에 걸맞은 인증을 할 수 있을 것이다. 이에 2차 인증에 기존의 인증서나 id/password, 또는 group key같은 번거로운 것을 이용하지 않고 Cyber-Physical-Social System을 사용한다면 user의 편리성을 더 증가시킬 수 있을 것이다. 본 연구에서는 Cyber-Physical-Social System기반의 인증에 관한 연구를 진행하려 한다.

The motion control of the divertor maintenance system of the China Fusion Engineering Test Reactor (CFETR) was studied in this paper, in which CFETR Multi-Functional Maintenance Platform (MFMP) was simplified as a parallel robot for the convenience of theoretical analysis. In order to design the motion controller of parallel robot, the kinematics analysis of parallel robot was carried out. After that, the dynamic modeling of the hydraulic system was built. As the large variation of heavy payload on MFMP and highly nonlinearity of the system, A Fuzzy-PID controller was built for self-tuning PID controller parameters by using Fuzzy system to achieve better performance. In order to test the feasibility of the Fuzzy-PID controller, the simulation model of the system was built in Simulink. The results have showed that Fuzzy-PID controller can significantly reduce the angular error of the moving platform and provide the stable motion for transferring the divertor.
