“…HiL is a very general term and the inclusion of hardware does not specify to which degree hardware has been used. For instance, it doesn't distinguish between a simulation that includes vehicle electronic control units (Alles et al 1992) and when a radio car is included or a case where a complete car powertrain is included as in Paper C. To further specify what is meant by HiL other terms are sometimes used. For example within driving simulation the term human-in-the-loop is used at times.…”

Modern vehicles are complex systems. Different design stages for such a complex system include evaluation using models and submodels, hardwarein-the-loop systems and complete vehicles. Once a vehicle is delivered to the market evaluation continues by the public. One kind of tool that can be used during many stages of a vehicle lifecycle is driving simulators.The use of driving simulators with a human driver is commonly focused on driver behavior. In a high fidelity moving base driving simulator it is possible to provide realistic and repetitive driving situations using distinctive features such as: physical modelling of driven vehicle, a moving base, a physical cabin interface and an audio and visual representation of the driving environment. A desired but difficult goal to achieve using a moving base driving simulator is to have behavioral validity. In other words, "A driver in a moving base driving simulator should have the same driving behavior as he or she would have during the same driving task in a real vehicle.".In this thesis the focus is on high fidelity moving base driving simulators. The main target is to improve the behavior validity or to maintain behavior validity while adding complexity to the simulator. One main assumption in this thesis is that systems closer to the final product provide better accuracy and are perceived better if properly integrated. Thus, the approach in this thesis is to try to ease incorporation of such systems using combinations of the methods hardware-in-the-loop and distributed simulation. Hardware-inthe-loop is a method where hardware is interfaced into a software controlled environment/simulation. Distributed simulation is a method where parts of a simulation at physically different locations are connected together. For some simulator laboratories distributed simulation is the only feasible option since some hardware cannot be moved in an easy way.Results presented in this thesis show that a complete vehicle or hardwarein-the-loop test laboratory can successfully be connected to a moving base driving simulator. Further, it is demonstrated that using a framework for distributed simulation eases communication and integration due to standardized interfaces. One identified potential problem is complexity in interface wrappers when integrating hardware-in-the-loop in a distributed simulation framework. From this aspect, it is important to consider the model design and the intersections between software and hardware models. Another important issue discussed is the increased delay in overhead time when using a framework for distributed simulation.

The design of spacecraft attitude control is important during the manufacture of spacecraft, and it is need to be validated adequately. To get the digital simulation validation of attitude control system, this paper discussed the spacecraft attitude control simulation system based on STK, Matlab and ADAMS. Based on the simulation frame, the paper analyzed the simulation model inter-clock. and realized the simulation system clock synchronization mechanism and algorithm. Based on the method of clock synchronization, the clock synchronization and logic correctness of message among multi-disciplinary simulation models could be ensured.

“…Final construction of aerospace power conversion systems is extremely costly while traditional software-only simulation [1]- [5], which is necessary to help the engineers optimize the system architecture, component choices and the system performance in terms of efficiency, power density, cost and lifetime, is often insufficient to exactly capture the control dynamics. One way to bridge the gap between simulation and final system construction is real-time hardware-in-the-loop (RT-HIL) testing [6], [7]. This solution increases the realism of the simulation and provides access to hardware features currently not available in the software-only simulation.…”

Digital control technologies are becoming increasingly attractive to power electronics controls in managing many power conversion systems due to many advantages over analog controls. Final construction of aerospace power systems is extremely costly while traditional software-only simulation is often insufficient to exactly capture the control dynamics. One way to bridge the gap between simulation and final system construction is real-time hardware-in-the-loop (RT-HIL) testing, which increases the realism of the simulation and provides access to hardware features currently not available in the software-only simulation. In this paper, we develop a digital power controller for aerospace applications and validate the design through hardware-in-theloop testing using Virtual Test Bed Real-Time (VTB-RT). The VTB-RT provides a low-cost, multi-solver, multi-platform tool forRT-HIL testing. Prior to the final system construction, the RT-HIL platform provides an approach to test the actual control software running on a dedicated processor with a virtual prototype of the power conversion system, where the VTB-RT platform models the power conversion system while the code generated for the digital control system runs on the real control hardware. The design procedure with the VTB-RT is first reviewed. The testing results are given and analyzed in the paper.
