The emergence of embedded systems is driven by technological evolutions that reshape the general conception about smart connectivity, modularity, or intelligent computing. Such trends suppose technology matures and versatile interconnection-communication abilities where the cost-benefit case becomes obvious. This paper presents a specially developed embedded system that fulfills most of the above expectations. The heart of this hardware topology is an FPGA-based Genesys Virtex-5 ready-to-use development board. This development system has been interfaced to a power electronic module specially conceived to drive twin DC motors. Obviously, both open- and closed-loop motor control is allowed by this electronic configuration. The software layer of the embedded system was designed by using last generation technology based on a MicroBlaze soft-core processor. All development steps have been gradually unfolded under main frame of the Xilinx EDK toolkit. As result, a compact and modularly embedded system has been obtained, well suited for a wide range of industrial servo control or automotive applications. Such developments may serve as useful guidance for future high performance and real-time computing embedded systems implementation.
Inverter technology plays a critical role in converting DC power to AC power for various applications, including renewable energy systems and portable devices. This study addresses the development of an Arduino Nano-based inverter and evaluates its performance compared to the commercial EGS002 inverter under no load, resistive, inductive, and capacitive load conditions. The methods involved waveform analysis and electrical parameter measurements, including output voltage, input and output currents, frequency, and duty cycle, to assess stability and efficiency. Results demonstrate that the Arduino Nano inverter maintains stable output voltages near the nominal 220 V AC with consistent sinusoidal waveforms across all load types. Under no-load conditions, it exhibited a lower input current of 1.091 A compared to 1.230 A for the EGS002, indicating higher efficiency. For the resistive load, both devices delivered output voltages around 192–195 V with comparable input currents near 4.070 A. Under inductive load, the Arduino Nano maintained a Vrms of 207.49 V and input current of 2.462 A, closely matching the EGS002. Capacitive load testing showed stable voltage output near 204 V with minimal waveform distortion for both inverters. This research concludes that the Arduino Nano inverter is a viable, cost-effective alternative to commercial inverters, capable of reliable performance under diverse load conditions. The novelty lies in demonstrating that a low-cost microcontroller platform can achieve competitive inverter performance, supporting flexible and efficient power conversion solutions.
Finite Control Set Model Predictive Control (FCS-MPC) is widely used in DC motor drive systems due to its fast dynamic response and simple control structure. However, conventional FCS-MPC often leads to excessive armature current and torque peaks during startup and transient operating conditions, which may exceed the motor’s rated limits and cause thermal stress or damage to the motor windings.in addition, the voltage stagnation phenomenon can degrade control performance and dynamic behavior. This paper presents an Enhanced Finite Control Set Model Predictive Control (EFCS-MPC) strategy for DC motor drives supplied by an H-bridge converter, that explicitly incorporates physical constraints, an extended finite voltage set, and a dominant speed-tracking term to predict future system behavior for each admissible switching state, and an optimized cost function is used to select the optimal control action directly applied to the converter. The proposed approach EFCS-MPC effectively limits the armature current, improves reference tracking accuracy, and significantly reduces steady-state speed and current ripple while preserving fast transient response, that enhances operational safety suitable for practical high-performance DC motor drive applications.
The Mobile Ad Hoc Networks (MANETs) are dynamic and infrastructure-less wireless networks where the devices are resource constrained and the topology changes rapidly. In the development of routing protocols in MANETs, it is very important to optimize parameters such as bandwidth, hop count and reduce energy usage. This paper introduces a new multi-objective routing protocol (NMORP) that will improve the performance and efficiency of MANET. The proposed protocol employs a composite cost scheme that considers a variety of metrics (energy, bandwidth, hop count) to guide routing choices in heterogeneous networks. We deploy NMORP in OMNeT++/INET and make comparisons to the conventional Destination-Sequenced Distance Vector (DSDV) protocol. The simulation outcome demonstrates that NMORP is superior to DSDV: network lifetime increases by a factor of up to 41%, throughput increases by approximately 32%, the end-to-end delay is minimized by up to 90%, and Packet Delivery Ratio (PDR) becomes more than 98% in certain situations. These advances indicate that NMORP can efficiently use its resources and provide credible data transfer across different conditions, which outlines the significance of multi-metric routing plans in the next-generation MANET design.
This paper presents the design and development of a functional ionic propulsion prototype system based on the electrohydrodynamic (EHD) principle, with the main objective of understanding and evaluating the mechanism responsible for ionic wind generation. The study does not focus on the actual motion of bodies, but rather on the fundamental physical phenomenon underlying the ionic propulsion and on identifying the design parameters that influence the system performance. To this end, several emitter-collector configurations were designed and tested using High-Voltage power supplies in the 10-15 kV range. The experimental measurements showed that the velocity of the ionized air varies as a function of electro geometry and electric field intensity. The result confirms the operation of the prototype and highlights several critical factors involved in the ionic wind generation including the distance between the electrodes, their shape material, as well as the stability of corona discharges. Fortis reason the paper can be regarded as an important preliminary step toward the future development of ionic propulsion system for practical applications, providing a useful experimental basis for geometry optimization and for improving the efficiency of EHD devices.
