This article presents a model library of generic components to build virtual Avionics Full Duplex Switched Ethernet (AFDX) networks. The presented library is a blockset for MATLAB/Simulink. The functional behavior of the simulation library's basic building blocks represent the scheduling and routing in AFDX end systems and switches on frame level. The graphical nature of Simulink allows to model AFDX...
This paper presents an automatic airport check-in KIOSK system. This work is done collaboratively by four subsystems, which are Airline Reservation, Credit Card Verification, KIOSK and Customer Command Input, in an action interactive manner. To reduce the risks or issues that often occur in complicated systems, a Four Subsystems in Parallel (FSIP) method has been proposed. Customers can benefit generality...
ARINC 429 is a widely used bus standard in signal transmission of aeronautical electronic devices on civil aircraft. According to the analysis of ARINC 429 bus protocol and parameter characteristics, the thesis designs and implements synchronous and real-time simulation of multi-channel's 429 signals, coming from subsystems of a certain type of airplane. On the basis of simulation result, the author...
In this work, we investigate in a Hardware-in-the-Loop (HiL) approach to solve the problems and opportunities created by the control of large numbers (hundreds to thousands) of MEMS sensors and actuators. Using HiL simulation, one or several devices of the system are used instead of their simulated models. HiL simulation is supposed to achieve a highly realistic simulation of equipment in an operational...
The software defined radio (SDR) channel simulator is designed and implemented in the FPGA for various wireless communication systems. The dedicated short range communications (DSRC) and ultra-wideband (UWB) channels are carried out to observe the characteristics of multi-path fading channels and validate the correctness of the SDR channel simulator. The hardware reconfiguration of the fading channel...
In today's aircraft, system complexity increases are making it particularly challenging for engineers to validate systems architectures. To ease this burden, the integration test rig, often known as the ldquoiron birdrdquo integration simulator, has been developed, and allows testing of real systems in a simulated environment.
This paper builds on previous work on optimal methodologies for the design of numerical subsystems for non-linear, uncertain hardware-in-the-loop (HWIL) simulators. Firstly, three important extensions to the existing methods are presented: the limitation to SISO systems is removed, allowing full MIMO design; a method for the design of an important and previously neglected component of the numerical...
