Energy harvesting from ambient sources has been the subject of several studies. Some of the proposed approaches attempt to generate electrical energy from the human movement. However, many of them can be uncomfortable or they impose a significant burden on the person’s gait. In the current article, the design of a hardware in-the-loop simulator for an energy-harvesting backpack is presented. The idea is based on the energy produced by a suspended load that moves vertically on a backpack while a person walks. The energy created from such a linear system can be maximised when it resonates with the walking frequency of the person. However, such a configuration can also cause great forces to be applied on the back of the user. The system that is proposed here consists of a mass attached on a rucksack, which is controlled by a motor in order to simulate the suspended-load backpack. The advantage of this setup is the ability to test different settings, regarding the spring stiffness or the damping coefficient, of the backpack harvester, and study their effect on the energy-harvesting potential, as well as on the human gait. The present contribution describes the design, analysis and preliminary testing of the hardware in-the-loop backpack system.

Digital simulation, hardware in the loop (HWIL) simulation and experiments of target practice were recognized as being powerful tools in checking the performances of laser homing guided weapons (LHGWs). Nevertheless, there was an indentation between simulation in lab and experiments of target practice, and there was not an effective experiment method to analyze the failed experiments of target practice. Based on the platform of rocket sled, this paper presented the project and design of L the HWIL simulation system for some type of LHGWs which has two main functions. The paper exhaustively discussed how to apply the rocket sled technology to flight simulation for laser-guided weapon. The theoretical predictions indicate that the proposed strategies are feasible for the performance checking and repeat of failed experiments, and that the system is an excellent transition from simulation in lab to experiments of target practice.

In this work, a novel test concept Radio hardware in-the-loop (RadioHIL) for next generation automotive electronic control units (ECUs) with wireless interfaces is proposed. The resulting test environment is well suited for ECUs networking with wireless sensors, actuators, mobile terminals or even with other vehicles and infrastructure elements. The presented RadioHIL approach is based on Software Defined Radio (SDR) architecture. The first step for executing the RadioHIL concept is the implementation of a multi-standard waveform design for automotive relevant purposes. Therefore the model-based implementations of two compliant IEEE 802.11b and 802.11p SDR transmitters are outlined, which are of interest for vehicular wireless communication. The emulation concept is demonstrated on the Universal Software Radio Peripheral (USRP) SDR platform.

This works presents a control strategy for a dc microgrid intended to operate in both grid-connected and islanded modes with smooth transitions between them. The dc microgrid is composed of photovoltaic (PV) generation, fast Electric Vehicle Charging Station (EVSE), low voltage dc loads, and a Battery Energy Storage System (BESS). All converters are connected into a single 700 V dc bus that interfaces with the ac grid through a 3-φ bi-directional ac-dc converter. Moreover, the microgrid operates under the Net Zero Energy (NZE). The proposed strategy comprises primary and secondary control levels. Primary level corresponds to the control of ac-dc and BESS converters considering parallel operation while secondary level to the control of the power exported to grid to achieve NZE operation. The system is validated through hardware-in-the-loop simulation in the Typhoon HIL 604 platform with the control strategy implemented in a DSP. Real-time simulation results are presented for several operation conditions during normal operation and the transition between the operation modes. © 2023 IEEE.

This study presents a simulation platform for a hybrid electric motorcycle with an engine, a driving motor, and an integrated starter generator (ISG) as three power sources. This platform also consists of the driving cycle, driver, lithium-ion battery, continuously variable transmission (CVT), motorcycle dynamics, and energy management system models. Two Arduino DUE microcontrollers integrated with the required circuit to process analog-to-digital signal conversion for input and output are utilized to carry out a hardware-in-the-loop (HIL) simulation. A driving cycle called worldwide motorcycle test cycle (WMTC) is used for evaluating the performance characteristics and response relationship among subsystems. Control strategies called rule-based control (RBC) and equivalent consumption minimization strategy (ECMS) are simulated and compared with the purely engine-driven operation. The results show that the improvement percentages for equivalent fuel consumption and energy consumption for RBC and ECMS using the pure software simulation were 17.74%/18.50% and 42.77%/44.22% respectively, while those with HIL were 18.16%/18.82% and 42.73%/44.10%, respectively.

End-to-end validation process for the INTA-Nanosat-1B Attitude Control System

This paper describes the end-to-end validation process for the Attitude Control Subsystem (ACS) of the satellite INTA-NanoSat-1B (NS-1B). This satellite was launched on July 2009 and it has been fully operative since then. The development of its ACS modules required an exhaustive integration and a system-level validation program. Some of the tests were centred on the validation of the drivers of sensors and actuators and were carried out over the flying model of the satellite. Others, more complex, constituted end-to-end tests where the concurrency of modules, the real-time control requirements and even the well-formedness of the telemetry data were verified. This work presents an incremental and highly automatised way for performing the ACS validation program based on two development suites and an end-to-end validation environment. The validation environment combines a Flat Satellite (FlatSat) configuration and a real-time emulator working in closed-loop. The FlatSat is built using the NS-1B Qualification Model (QM) hardware and it can run a complete version of the on-board software with the ACS modules fully integrated. The real-time emulator, running on an industrial PC, samples the actuation signals and emulates the sensors signals to close the control loop with the FlatSat. This validation environment constitutes a low-cost alternative to the classical three axes tilt table, with the advantage of being easily configured for working under specific orbit conditions, in accordance with any of the selected tests. The approach has been successfully applied to the NS-1B in order to verify different ACS modes under multiple orbit scenarios, providing an exhaustive coverage and reducing the risk of eventual errors during the satellite's lifetime. The strategy was applied also during the validation of the maintenance and reconfiguration procedures required once the satellite was launched. This paper describes in detail the complete ACS validation process that was perfor

Results from laboratory experiments on a pre-tensioned heaving buoy of 8.4 m diameter, tested at scale 1:16 is presented. The wave energy converter, which is under development by the Swedish company CorPower Ocean, is designed with a passive pneumatic machinery component referred to as WaveSpring, invented at NTNU. The negative spring arrangement inherently provides phase control. The power take off system and the effect of the phase-enhancement component was represented by a motor rig run with a force-feedback controller. Responses with and without the WaveSpring unit were measured in order to compare performance in terms of motions, loads and power absorption. The experiments included decay tests, radiation tests, irregular wave tests with the system in normal operation, as well as extreme wave tests with the system in survival mode. The power was extracted through a linear damping force, where the damping coefficients were set close to their theoretical optimum for the heave mode. The results show that with the WaveSpring component, the system is able to absorb three times more power in realistic sea conditions than without it. This is achieved without increasing the damping force, thus giving a three times higher ratio of absorbed energy to PTO force. The maximum mooring line tension in storm conditions is found to be less than 2.5 times the pretension force. (C) 2016 Elsevier Ltd. All rights reserved.

To improve fuel economy of a novel series-parallel hybrid electric bus (SPHEB) further, the control rule of battery power distribution is derived from the offline optimisation algorithm based on Pontryagin's minimum principle, internal relationship between the equivalence fuel factor. and trend of state of charge (SOC) with different driving condition is established and calculation model of SOC is formed. On the basis of the above, according to the feature of the city bus driving cycle, the algorithm of adaptive fuzzy sliding-mode control (AFSMC) is introduced to periodically update the equivalence fuel factor, and then the power-balancing adaptive control strategy is developed. To validate the proposed strategy rationality, the hardware in-the-loop integrated with bench test is applied to compare the proposed control strategy with the previous optimal control strategy. The results indicate that the efficiency of SPHEB system is improved by the proposed control strategy.
