Vision-based navigation technologies are currently under development in order to support future planetary exploration missions to the Moon, Mars and small bodies. By tracking landmarks and local features on the surface of celestial bodies, these technologies will provide GPS-like spacecraft localization capabilities and enable precision orbiting and/or landing toward known targets of interest. In order to contribute to the development roadmap of these technologies, this paper will present the simulation Infrastructure for Autonomous Navigation technologies (SIAN) aiming at simulating with hardware-in-the-loop and high repeatability vision-based terrain relative navigation algorithms. This scaled simulation infrastructure aims at bridging the gap between pure software simulations and expensive helicopter or rocket-based flight tests. This paper will present the main objectives of this innovative and unique simulation infrastructure and report its conceptual and detailed design.

An approach to streamline the hardware-In-the-loop (HWIL) simulation development process is under evaluation. With increased microprocessor speed, FPGA capacity and increased bus bandwidth over the last decade, a common interface design may be able to support a large number of HWIL interfaces that were previously custom designed interfaces. The Common HWIL approach will attempt to provide a more flexible, scalable system. The overall goal of the Common HWIL system will be to reduce cost by minimizing redundant development and operational labor and equipment expenses. This paper will present current results and future plans of the development.

Precision of positioning and operation are enormously affected by vibration while flexible manipulator is running. Great attention has been paid on the research on vibration control of flexible manipulator. However, there is shortage of effective and uniform real-time simulation platform to date. Based on the study of coupled modeling and dynamic characteristics, the two-link flexible manipulator system made of piezoelectric smart structure was established. The manipulator’s motion was controlled by single-chip computer system and serial communication module provided by simulink. The date exchange between manipulator system and the MATLAB workspace was implemented by the data acquisition module, which combined physical system with virtual environment. So the real-time simulation system for vibration control of flexible manipulator was set up. Adopted the PID control algorithm, the entire experimental system was debugged. The results showed that the system can work normally, and the PID control algorithm can also effectively suppress the vibration of flexible manipulator. The platform can be used for vibration control experimental research and the actual system.

This paper presents a new method for the design and validation of advanced driver assistance systems (ADASs). With vehicle hardware-in-the-loop (VeHIL) simulations the development process, and more specifically the validation phase, of intelligent vehicles is carried out safer, cheaper, and more manageable. In the VeHIL laboratory a full-scale ADAS-equipped vehicle is set up in a hardware-in-the-loop simulation environment, where a chassis dynamometer is used to emulate the road interaction and where robot vehicles are used to represent other traffic. In this controlled environment the performance and dependability of an ADAS is tested to great accuracy and reliability. The working principle and the added value of VeHIL are demonstrated with test results of a driver information and warning system. Based on the 'V' diagram, the position of VeHIL in the development process of ADASs is illustrated. (C) 2009 Elsevier Ltd. All rights reserved.

The determination of aircraft stability and control derivatives from wind-tunnel and computational fluid dynamics data can be an expensive and time-consuming procedure. This case study shows how linear system identification techniques can be used to obtain this information with sufficient accuracy to design a satisfactory flight control system for an aerial target of the Royal Thai Air Force. Just one flight was undertaken, using a racetrack manoeuvre, to provide the data for identification and validation. The system parameters were identified and a flight control system was designed. hardware-in-the-loop simulation was used to perform initial tests on the controller and to test the control system hardware and software. A second flight was performed to test the resulting controller, and a satisfactory performance was obtained without the need to adjust the controller gains.
