All hardware-in-the-loop (HWIL) missile simulations use motion platforms that position the missile seeker and simulated target to relative positions and motions that reproduce a live engagement. These motion platforms...

A testbed of a series hybrid vehicle was built up at the University of Paderborn to allow studying the design, implementation, and optimization of operating strategies for hybrid vehicles. The paper will present a hierarchical control structure of a series hybrid drive train. Due to the fact that the overall efficiency of the hybrid drive train depends very much on the operating conditions, e.g., the kind of route (inner city or highway) or the kind of driver (sporty of conservative) an adaptive energy management will be presented that takes into account these various uncertainties and increases fuel economy and derivability. simulation results will be presented as well as a hardware-in-the-loop testbed configuration of this series hybrid vehicle.

An optical signal injector (OSI) system has been developed for use in the hardware-in-the-loop (HWIL) testing of laser radar (LADAR) seekers. The OSI, in conjunction with a scene generator, generates optical signals simulating the return signals of a LADAR seeker and delivers them to a Unit Under Test (UUT). The signals produced by the OSI represent range and intensity (reflectivity) data of a target scene from a given HWIL scenario. The OSI has a modular architecture to allow for easy modification (e.g., operating wavelength, number of optical channels) and is primarily composed of commercial off-the-shelf (COTS) components to improve reliability and reduce cost, Presented here is a description of the OSI and its capabilities.

This paper describes the cumulative status to-date, and current developments in the British Aerospace IR scene projector system technology in early 1997. The systems have been developed for hardware-in-the-loop (HWIL) simulation in missile test and evaluation facilities. Historically, the technology has been called ''Thermal Picture Synthesis'' an early equivalent of what is now known as Infra-red Scene Projection (IRSP). Earlier generations of system were based on a monolithic resistor-substrate construction, a modification of which is still used for ground target simulations (TPS3), whereas the more recent systems for air target simulations are based on fully suspended resistor designs (TPS4). These projector systems incorporating full scale arrays have been fabricated at up to 256 x 256 complexity. Research work is being carried out on high temperature arrays for air-to-air countermeasure simulations, and the first TPS5 full system at 512 x 512 complexity has completed its design stage and has recently moved into fabrication. Research testbed arrays of 768 x 768 have just been made, and 1024 x 1024 arrays are presently being fabricated. The paper includes an initial introduction to the basics of the technology, and is followed by a section on certain specialised features to combat inherent issues in the technology. Specifications and the current status of each category of device is then given.

This is the second in a series of papers describing an on-going investigation into the detailed performance of our resistor array infra-red scene projector devices and systems. The purpose is to extract understanding and information which will enable validation of simulations involving the systems, and design compromises to be resolved. Following last year's conclusions, the importance of Non Uniformity Correction is reinforced and the concept of Local Step Error and its importance is developed and investigated practically. A test methodology is developed, and the first steps in practical measurements are reported.

The integration of mechanical systems and microelectronics opens many new possibilities for process design and automatic functions. After discussing the mutual interrelations between mechanical and electronic design the different ways of integration within mechatronic systems and the resulting properties are described. The information processing can be organized in multilevels, ranging from low-level control, through supervision to general process management. In connection with knowledge bases and inference mechanisms intelligent control systems result. The design of control systems for mechanical systems is described, from modeling, identification to adaptive control for nonlinear systems. This is followed by solving supervision tasks with fault diagnosis. Then design tools for mechatronic systems are considered and examples of applications are given, like intelligent control of an electromechanical throttle actuator and force and torque reconstruction for a robot.
