This paper describes the techniques employed in the development of a VHDL-based system simulation of the Honeywell RH32 Prototype Development Unit (PDU). The architecture of the PDU is briefly described, and a design process is presented. The system simulation approach is discussed, including simulation model types, their development and validation, and testbench structure. Additionally, techni...

Recent design and verification languages, such as SystemVerilog, support a rich test bench language, which provides significant support towards developing layered, structured, constrained random test bench architectures. Typically, the test bench language offers many features that are not synthesisable and therefore cannot be carried into the hardware for hardware accelerated simulation. One of...

Non Destructive Testing applied to railway axles is performed both in production and in maintenance. During production, NDT is carried out at different stages adopting different techniques, while during maintenance (in-service inspection) only ultrasonic testing is usually carried out. The present paper is focused on some aspects of calibration related to the in-service inspection of railway ax...

The decoupled control of torque and flux has made field-oriented control an attractive choice for high performance induction motor drives. However, changes in the speed tracking trajectory and external disturbances make it difficult to achieve an acceptable closed-loop tracking performance, especially when traditional linear controllers are used. This paper addresses this issue by applying dire...

The present research is focused on developing embedded intelligent structures for energy management in mobile systems. The research introduces a hybrid structure composed of different energy sources endowed with control systems able to optimize the power flow of the ensemble. In the paper, the architecture of the proposed hybrid system is described. To test the functionality and the advantages ...

As part of the new standards on automotive fuel consumption and pollution, SIMBA project brings togetherseveral automotive air loop supplier around a common goal : to develop a simulation tool of the automotive airloop which takes into account the interactions between components, and will enable to improve performanceof the whole system.In this project, FEMTO-ST institute wa...

The head-tail instability of the 12 GeV PS at KEK, has been confirmed by extensive experiments. It turns out that the eddy-current-induced sextupole fields in the rectangularshaped vacuum pipe in the main bending magnets played a crucial role in the head-tail instability during acceleration. The eddy current effect was verified by field measurement and chromaticity measurement in a way of diffe...

MARVEL is a Leonardo da Vinci project that provides a framework to analyse the pedagogic effectiveness of online labs in various heterogeneous areas that include solar energy, robotics, electronics and electro-pneumatics. It is also used as a test bench to compare the implementation of purely remote labs, where all devices are real, versus mixed-reality environments, where real devices work tog...

A two-stage compression variable frequency air source heat pump is proposed combining variable frequency technology with two-stage compression cycle. The empirical formula of optimal intermediate pressure is calculated, and two-control-model with the priority target as coefficient of performance (COP) or heating capacity is advanced in this paper. A test bench is developed for the two-stage com...
