The flight control system is the integrated command center and core component of the UAV system. Aiming at the problems of poor accuracy and low efficiency in the field measurement of flight control system parameters, combined with the configuration of the flight attitude sensor-vertical gyroscope, hardware-in-the-loop simulation technology, and integrated automatic test methods are adopted. The hardware-in-the-loop simulation test platform for the UAV flight control system composed of a low-cost, high-precision miniaturized UAV attitude calibration platform and a control piston deflection angle test device is designed. The main controller replaces the ground master control station of the UAV and directly sends remote control commands to the aircraft. By changing the attitude of the aircraft, and measuring the voltage of the control signal, the feedback signal, and the rudder angle, the comprehensive performance test of the parameters of the flight control system is realized. The performance test of the platform shows that the platform can meet the test requirements of angular position, system voltage, and control piston deflection angle.

The escalating interest in renewable energy sources has spurred a demand for innovative approaches to electricity generation. Notably, marine hydrokinetic turbines have emerged as a promising solution, capable of providing cost-effective power to locations isolated from traditional grids. Among these turbines, ocean current turbines (OCTs) stand out for their ability to harness the vast energy potential stored within open ocean currents. This research paper delves into the realm of marine energy, focusing on the modeling and simulation of OCTs using a hardware-in-loop (HIL) simulation approach with the aid of an OPAL-RT environment. The experiment recreates realistic operating conditions to evaluate the turbine’s feedback performance in the real-time simulator. The research progresses to explore a grid-integrated scenario where the OCT system’s response to water flow speed changes is evaluated as a blade pitch controller is tested. Power generation profiles are recorded from the simulated grid to demonstrate grid integration capabilities. The results validate the effectiveness of the OPAL-RT platform for power HIL emulation of marine energy systems and contribute to advancing the technology required to make ocean current turbines a viable renewable energy source with the potential to sustainably meet the world’s growing power demand.

This paper introduces a vision-based dynamic positioning (DP) control system and develops a hardware-in-the-loop (HIL) platform to validate the performance of the controller applied to a work-class remotely operated vehicle (ROV). The proposed platform consists of three main parts: hardware, image processing part and controller. The hardware included a calibrated camera that was connected to a dedicated computer via USB 2.0. In the image processing part after pre-processing a circular Hough transform was used to detect and determine the position of the target in the image plane. Furthermore, this paper proposed a feedforward proportional-integral-derivative (PID) controller. To evaluate the performance of the proposed controller, two scenarios were implemented. In the first scenario, the target was considered stationary and a disturbance was applied to the ROV in the simulation environment. In the second scenario, the target object has moved along a rectangular path, and the objective was to stabilize the ROV at the desired points. In both scenarios, the reference signal was acquired by a calibrated camera from the target and sent to the controller. The results showed the desirable performance of the proposed controller.

This paper presents an evaluation method for accessing a RoboGuide virtual robot cell and establishing control over a PLC-integrated robot system, with the primary objective of enhancing industrial automation capabilities. The experimental setup encompasses the simulation of a virtual robot cell featuring four Fanucs robots and two part conveyor belts, all controlled through Allen-Bradley PLC-based systems and a Human Machine Interface (HMI). This technological framework enables the testing and validation of control code on simulated industrial systems, ultimately contributing to increased operational efficiency and productivity. The study not only outlines the essential components involved in various industrial sectors but also assesses their efficacy, offering valuable insights into practical applications. Emphasizing the critical role of quality control and assurance in the automation sector for ensuring product standards and safety, the paper describes a simulation created within RoboGuide. In this simulation, the robot and PLC establish full-duplex communication over an Ethernet TCP/IP protocol. A custom control panel is developed, connecting the HMI to the PLC, thereby enabling the execution of robot actions or teaching pendant programs within the simulation environment. The core objective of this research is to assess the functionality of an assembly line using hardware-in-the-loop (HIL) simulation prior to the implementation of Factory Acceptance Tests (FAT) and Site Acceptance Tests (SAT) in a real-world industrial setting.

Incorporating renewable energy sources and battery energy storage systems (ESS) into electrical distribution networks brought new approaches to energy management systems. This paper proposes a novel energy management system (EMS) scheme for a grid-connected residential microgrid. The designed EMS is composed of two interconnected layers. The upper layer contains a supervisory controller, based on a priority-based approach, to reduce microgrid operation costs while accounting for dynamic changes in household preferences and electricity price fluctuations. The lower layer employs Mixed Integer Linear Programming (MILP) optimization to solve the economic dispatch problem, considering the RES curtailment, the ESS management, the demand response mechanism, and the connection with the main grid. The developed EMS is tested and validated through a hardware-in-the-loop simulation using the OPAL-RT simulator. Applied on four different typical days over the year, the results demonstrate that the developed strategy can meet the varying energy needs of the microgrid, establishing an efficient power-sharing control between the loads, the energy storage system and the main grid. Further, the EMS exhibits an operational cost reduction ranging from 58 % in summer to 50 % in winter. Moreover, the MILP optimization is compared to particle swarm optimization (PSO) and linear programming (LP) to confirm the consistency of the proposed EMS.

5G network for railway (5G-R) emerges as a promising train-ground communication solution, concurrently facing ubiquitous connectivity and reliable transmission design challenges. This paper focuses on the impact of different channel models and Doppler effects on the physical layer transmission performance of the 5G-R communication system. Based on the 5G-R channel hardware-in-the-loop simulation platform, we measured and compared the performance of the 5G-R system in terms of bit error rate (BER) and error vector magnitude (EVM) across different scenarios. The measurement results reveal that non-line-of-sight propagation and Doppler effects during high-speed movement contribute to the deterioration of the system's BER and EVM. Nevertheless, enhancing the signal-to-noise ratio can mitigate the impact of these factors to some extent.
