hardware-in-the-loop (HIL) simulations are more and more used to assess performances of electric drives before their insertion on a whole system. But HIL simulation requires a lot of subsystems and control parts. A graphical description is used in this paper in order to organise HIL simulation. Two examples are given with experimental results: an electric vehicle traction system and a wind generator.

A multimodal operator interface station is developed to display a realistic virtual reality depiction of a compact excavator performing general digging tasks. The interface station includes engine audio feedback and a near life-size operator display attached to a full-size cab. The excavator dynamics are determined by models of the hydraulic system, the linkage system, and the soil digging forces. To maximize the fidelity of the hydraulic model, certain "virtual" components of the model are replaced with real-time hardware-in-the-loop (HIL) simulations of the actual hardware. HIL simulation is done in a geographically isolated facility, with Internet based communication between HIL and the Remote Operator Interface. This is the first reported high-fidelity operator interface to be combined with remote hydraulic HIL simulations.

An architecture for Robotic hardware-in-the-loop simulation (RHIELS) has been proposed as a design and simulation tool for serial-link robot manipulators [1]. This paper evaluates the RHILS platform's capabilities when applied to the simulation of the 5-d.o.f CRS Catalyst-5 industrial manipulator from Thermo Fisher Scientific Inc. The results demonstrate that the RHILS platform is able to accurately simulate the robot even under extreme operating conditions, and the platform shows significant potential as a design tool for both the robot and its control unit.

This paper proposes an alternative method for the coordination of overcurrent protection devices by using an adaptive scheme. This scheme is described as well and validated through two co-simulation techniques: the Real Time simulation (RT) and the hardware-in-the-loop simulation (HIL). These techniques require the integration of different software and hardware platforms as PSAT (R) and LABVIEW (R). The results of the integration are presented applying the methodology to the IEEE 13-Nodes test system. Then, the information delivered by the RT-HIL simulation is compared and validated whit the off-line software ETAP (R). The RT-HIL simulation methodology proposed in this paper can be used as a platform for testing and validation of smart grid algorithms.

CAN sees wide use in the aerospace industry, and is proposed as the link-layer implementation of the proposed Aeronautics Radio, Incorporated 825 protocol standard (ARINC-825). Unfortunately, CAN receives far less attention in aerospace than in the automotive domain;consequently, the aerospace security research community has been unable to assess the vulnerabilities of this protocol, due to a lack of access to data and real-time simulation infrastructure. We introduce ARINC-825TBv2, a hardware-in-the-loop link-layer simulation platform that allows aerospace security researchers to observe ARINC-encoded CAN traffic with realistic data. We present a novel, predictive attacker Gaslighter that we integrate into the testbench, and demonstrate its effectiveness. Furthermore, we implement an intrusion detection algorithm from the literature, Z-Score, and validate it using Gaslighter and realistic CAN data. We show that as the number of messages in the simulation increases, the accuracy of Z-Score drops to below that of a random predictor.

The Unmanned Underwater Vehicle (UUV) is used more and more widely in military and non-military areas. Since UUV's navigation and motion control system is highly complex, a hardware-in-the-loop simulation (HILS) system is designed and implemented to help research and development of its navigation and motion control system. The HILS system is mainly composed of real-time simulation computer, main control compute, GPS/Beidou satellite signal simulator, three-axis turntable, actuator load simulator, water pressure simulator, acceleration simulation unit, visual computer and interface devices. Performance specifications are allocated to each components of the HILS system according to dynamic characteristics of the UUV under complicated disturbances. Proximity between the results of the UUV's HILS and sea trial demonstrates the validity of the HILS system elementarily.

In a system of systems (SoS) consisting of heterogeneous independently operable systems, successfully sending, receiving, and understanding data is necessary to achieve interoperation among the systems. Extensible Markup Language (XML) is applied to wrap the data in a way that is commonly understood in the SoS while the asynchronous nature of the interactions among systems is viewed as an event driven system. Discrete event specification (DEVS) formalism is used to describe the models composing the SoS. simulation provides a means to examine and analyze systems and their interactions as well as how a new system effects the SoS but can hide issues that arise during final implementation. hardware-in-the-loop (HIL) simulation provides a bridge between simulation and implementation in order to reduce build cost and more readily verify a system's desired performance. A Groundscout robot is used as a real system in the simulation of a robust threat detection scenario.

This paper presents the first application of the Robotic hardware-in-the-loop simulation (RHILS) platform developed to allow the analysis and synthesis of robot manipulators and their controllers. The RHILS platform was applied to the CRS CataLyst-5 manipulator from Thermo Fisher Scientific Inc., and then evaluated on its performance and usefulness as a simulation and design tool. Some conclusions are reached about the potential of the platform for use in research and industry, and plans for further development are outlined.

We propose a Convertible Static Transmission Controller (CSTC) concept that enables coordinated power flow control with emphasis on large penetration of renewable energy resources based transmission in a meshed network. CSTS can be connected across the substation power transformer and reconfigured for different modes of operation to perform as a versatile transmission controller with several functions including: power flow control for transmission of renewable resources, and as a transformer back-up for disaster management and/or life extension purposes. Different connecting configuration options, i.e. shunt-shunt, series-shunt, and series-series can be obtained. In this paper, we demonstrated the viability of the proposed concept using Typhoon HIL400 ultra-high fidelity hardware-in-the-loop (HIL) system in three different modes of operation. HIL simulations are used to verify the validity of the proposed control architecture for CSTC operation during both normal and unbalanced power system conditions for different connecting configurations.
