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...
The paper holistically discusses the analysis and simulation of simplified two diode model and its comparative analysis with the one and three diode models. The two diode model presented has been grounded on the interpretation of the output current equation. This model entails four parameters and condenses the complexity and the computational time considerably. I-V and P-V curves for two diode model...
Currently, the research of GIS and environmental models has made great progress, but the combination of both is still a difficulty. Aiming at the integration of GIS and environment model, the paper drew some functional components from open source geographic information system, and embedded the atmosphere environment model into GIS as application program interface by hybrid programming, achieved the...
The unmanned aerial vehicles (UAVs) has grown in military and civilian areas of application. Several industries (automotive, military, factories, space, etc.) use robots for dangerous and repetitive tasks. This paper is dedicated to a special type of aerial platforms, the quadricopter. This platform has been highlighted by having unique characteristics in flight and construction, for example, hovering...
In order to ensure the electricity output quality of one turbocharged diesel generator set under pulsed load, some measures were taken to control the speed regulating rate of original power machine. One main reason causing the big diesel speed regulating rate in experiment is the lack of air for combustion in the early period of pulse. The other reason is that the energy stored by set shafting parts...
According to the basic structure of the aircraft landing gear, through the mechanical analysis, we established the mathematical model of the aircraft landing gear of semi-active damping system, and a linear interpolation method was applied in the fuzzy controller queries to adjust the PID parameters automatically. We have used the Matlab / Simulink control system simulation software for aircraft landing...
The mechanical ventilator settings in patients with respiratory diseases like chronic obstructive pulmonary disease (COPD) during episodes of acute respiratory failure (ARF) is not a simple task that in most cases is successful based on the experience of physicians. This paper describes an interactive tool based in mathematical models, developed to make easier the study of the interaction between...
This paper presents a detailed control system building process for a hardware-in-loop micro-satellite simulator to apply and test system identification or control algorithms. It also designs a new system mechanism to combine the simulator with MATLAB Simulink by DDE, which can enable Simulink to directly control the simulator system and accomplish data sharing and real-time control function. Finally,...
Combining the state-space of generator and feedback control theory of stacker, conversion analysis research on the stacker state about normal operation from horizontal and vertical direction is done. Aiming at generator operating speed limits, the multi-speed control theory of stacker is proposed and the nonlinear speed model of speed was analyzed and abstracted. The assumption of abstract model is...
This paper studied the physical properties of multilayered corrugated board, fully considering the air-flow of flute influence on its properties. Built up the theoretical model of pre-compressed multilayered corrugated board. Used MATLAB/Simulink software simulate theoretical model to determine the value of acceleration during impact. In a qualitative way the simulated results tend to coincide with...
