“…For this purpose, trapezoidal rule is chosen. The trapezoidal rule [11], 129 [28], [29] has some special properties which make it stand out from the rest. It is able to track transients To use the NIS method, it is essential to define the numerical method with which the system equations will be discretized.…”

“…where V 1 , V 2 are the voltage differences, I 1 , I 2 are the currents, and N 1 , N 2 are the number of turns in primary and secondary windings, respectively. In the case of the full-bridge power inverter, an NIS-based approach, the Associated Discrete Circuit (ADC) model [27][28][29][30][31], is used to convert power electronics, high-frequency switching components in the power grid, to their respected Norton equivalents.…”

Smart grid technology is the next step to the evolution of classical power grids, providing robustness, reliability, and security throughout the network, enabling real-time management and control. To achieve these goals, distributed computing (microgrid concept) and intelligent control algorithms, tailored to the nature and needs of the network under study, are necessary. To deal with the vast diversity of power grids, being able to capture the dynamics of any given network, and create tools for network analysis, apparatus testing, and power grid management, an automatic design framework for real-time power system simulators is needed. In this article, a prototype of this approach is presented, employing Field Programmable Gate Array (FPGA) platforms due to their reconfigurability that enables low-power, low-latency, and high-performance designs, as a first attempt towards an open source platform, compatible with the majority of hardware design suites. It comprises two major parts: (i) a user-oriented section, built in Matlab/Simulink; and (ii) a hardware-oriented section, written in Matlab and Very High Speed Integrated Circuit (VHSIC)-Hardware Description Language (VHDL) code. To verify its functionality, two test power networks were given in a schematic format, analyzed through Matlab code and turned into dedicated hardware simulators with the aid of the VHDL template. Then, simulation results from Simulink and the prototype were compared for error estimation. The results show the prototype's successful implementation with minimal resources utilization, high performance and low latency in the order of nanoseconds in Xilinx 6-and 7-series FPGAs, therefore proving its modularity and efficient use in many different scenarios, meeting low-latency/real-time requirements while enabling further smart grid research.

“…One of the best system architectures for processing and controlling the autonomous systems is the Cyber Physical System (CPS-5C). The prominence of the CPS-5C architecture is the highdegree of flexibility to work in different autonomous applications such as in medical applications, automotive, smart cities, industrial, consumer, energy, robotics, infrastructure, transportation, and military [24][25][26]. As demonstrated in Figure 2, the CPS-5C architecture consists of 5 layers.…”

To keep up with today's dense metropolitan areas and their accompanying traffic problems, a growing number of towns are looking for more advanced and swift urban taxi drones. The safety parameters that must be taken into consideration may be the most important element in the widespread use of such technology. Most recent aviation mishaps have happened during the landing phase, making this a particularly important safety consideration for Vertical and/or Short Take-Off and Landing (V/STOL) drones. In this study, we focused on improving the fault tolerance of the processor architectures used by the predecessors of Autonomous Landing Guidance Assistance Systems (ALGAS), which in turn improves their decision-making capabilities. Furthermore, this is achieved by proposing a fault-tolerant processing architecture that depends on the Gamma Distribution Sliding Window Unit (GDSWU). This proposed GDSWU has been designed completely using VHDL, and the targeted FPFA was the Intel Cyclone V 5CGXFC9D6F27C7 chip. The GDSWU could operate at a maximum frequency of 369.96 MHz, as calculated by the synthesis results of the INTEL Quartus Prime program. The suggested GDSWU core only requires 20.36 mW for dynamic core and I/O power consumption.
