The Advanced simulation Laboratory (ASL) at Lockheed Martin Electronics and Missiles In Orlando, Florida, has developed and integrated a suite of-visualization tools designed to support and enhance hardware-in-the-loop simulation. State-of-the-art computer image generators with multiple channels and viewpoints using detailed, fully articulated models provide real-time views of the system under test. Workstations serve as symbol generators overlaying flight symbology and textual data on the virtual scene. A digital moving map displays mission progress, critical points and target symbology. A real-time data monitor program allows engineers to organize data logically for display during the run. National Instrument's LabView provides virtual gauges, meters, status indicators and even stripcharts. The ASL visualization tools are fully integrated into the lab video system. As a result, all visualization channels can be recorded and routed to any display in the lab including the multi-screen, multimedia demonstration and briefing room. Video routing and host control for the image generators, symbol generators and digital map are under control of a real-time, scripted visualization control program. These visualization techniques have been used successfully in two HWIL simulation projects and are considered an integral part of any future projects.

This paper presents an experimental approach for the verification of the physics-based phase variable model of electric machines developed using the parameters obtained from FE solutions. The experimental verification was performed through simultaneous simulation of the PM machine drive using the actual machine - a hardware-in-the-loop real time simulation approach and the physics-based phase variable model of the actual machine, respectively. A 6-pole PM machine was used to present the physics-based phase variable modeling;a 10-pole 42-V PM machine was used to demonstrate the experimental verification.

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.

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.

This paper builds a typical HILS system based on the xPC real-time simulation platform and designs the key function modules of HILS by C++. A digital model of actual three-phase asynchronous motor speed control system is built and the parameters of the controller are optimized with the simplex algorithm. The optimized control parameters were applied to the HILS real-time control strategy model and downloaded to the HILS target machine. The A/D and D/A conversion was realized through the hardware I/O board, realizing the real-time simulation of the actual motor speed control system. By comparing the digital simulation results with the HIL real-time simulation data and curve images, the accuracy and effectiveness of the designed HILS system are verified.

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.

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.

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.

We have designed and developed a way to incorporate hardware-in-the-loop (HIL) simulation into Model-Based Systems Engineering (MBSE) using Object-Process Methodology (OPM) ISO 19450. Implementing the HIL simulation in OPCloud, an OPM cloud-based conceptual and computational modeling framework, has enabled us to demonstrate industrial-strength capabilities. We describe the architecture of this OPM-HIL combined system and report on results with a real case study, in which the modeling encompasses stages starting with conceptual design and ending with HIL simulation and testing. This combination can serve as a basis for a model-driven systems operating system.

The paper presents a way of using hardware-in-the-loop simulation for the design of speed governors for hydraulic turbines. The mathematical model of a Kaplan turbine and the electrical power generator are built in a numerical simulation software (Simulink, AMESim, LabVIEW etc.), and the resulting system interacts with an actual electrohydraulic servomechanism. This allows an experimental test of the whole speed control system in a very close environment to the actual operating conditions without the need of an actual turbine and power generator on the test platform.
