Refimprove date June 2009 Real time simulation refers to a computer model of a physical system that can execute at the same rate as actual wall clock time. In other words, the computer model runs at the same rate as the actual physical system. For example if a tank takes 10 minutes to fill in the real world, the simulation would take 10 minutes as well. Real time simulation occurs commonly in computer game computer gaming , but also is important in the industrial market for operator training and off line controller tuning ref http www.vega group.com assets documents 10000421matlabsimulink.pdf The Succsssful development process with MATLAB Simulink in the framework of ESA s ATV project ref . Computer languages like VisSim and Simulink allow quick creation of such real time simulations and have connections to industrial displays and Programmable Logic Controllers via OLE for process control or digital and analog I O cards. Real time simulation in academic curricula Real time simulators are used extensively in many engineering fields. As a consequence, the inclusion of simulation applications in academic curricula can provide great value to the student. Statistical power grid protection tests, aircraft design and simulation, motor drive controller design methods and space robot integration are a few examples of real time simulator technology applications. ref http www.opal rt.com sites default files technical papers 2010 Intertech Dufour RTLABApplications.pdf Opal RT Technologies Technical Paper Real Time Simulation Technologies in Education a Link to Modern Engineering Methods and Practices ref References reflist External links http www.opal rt.com technical document what where and why real time simulation The What, Where and Why of Real Time Simulation Category Real time simulation ... more details

TargetLink requires an existing MATLAB Simulink model. TargetLink generates both ANSI C ANSI C , as well as production code optimized for specific processors. TargetLink also supports the generation of AUTOSAR compliant code for software components for the automotive sector. The management of all relevant information for code generation takes place in a central data container, called the Data Dictionary. The test of the generated code is implemented in Simulink , which was also used for the specification of the underlying simulation models. TargetLink supports three simulation modes to test the generated code Model in the loop simulation MIL In this mode the model design can be checked. The MIL is also known as floating point simulation, since there is typically a floating point variables. Software in the loop SIL The simulation is based on the execution of generated code, which runs on a PC system. The variables are typically plain or fixed point numbers. Processor in the loop PIL In the PIL, the generated code running on the target hardware or on an evaluation board. By including so called real time frames, it is possible to transfer the simulation results as well as memory consumption and runtime information to the PC. The Motor Industry Software Reliability Association MISRA published official MISRA modeling guidelines for TargetLink in late 2007, which are particularly important for functional safety of safety critical applications. In 2009, T V S D certified TargetLink for use during the development of safety critical systems to IS ... more details

Unreferenced date December 2006 expert subject electronics date June 2010 Electronic design comprises the analysis and synthesis of electronic circuits Methods To design any electrical circuit, either Analogue electronics analog or Digital circuit digital , Electrical engineering electrical engineers need to be able to predict the voltages and currents at all places within the circuit. Linear circuit s, that is, circuits wherein the outputs are linearly dependent on the inputs, can be analyzed by hand using complex analysis . Simple nonlinear circuits can also be analyzed in this way. Specialized software has been created to analyze circuits that are either too complicated or too nonlinear to analyze by hand. Circuit simulation software allows engineers to design circuits more efficiently, reducing the time cost and risk of error involved in building circuit prototypes. Some of these make use of hardware description languages such as VHDL or Verilog . Network simulation software More complex circuits must be analyzed with circuit simulation software such as SPICE and EMTP and many others. Linearization around operating point When faced with a new circuit, the software first tries to find a Steady state steady state solution wherein all the nodes conform to Kirchhoff s Current Law and the voltages across and through each element of the circuit conform to the voltage current equations governing that element. Once the steady state solution is found, the software can analyze the response to perturbations using piecewise approximation, harmonic balance or other methods. Piece wise linear approximation Software such as the PLECS interface to Simulink uses piecewise linear approximation of the equations governing the elements of a circuit. The circuit is treated as a completely linear network of Diode Shockley diode equation ideal diode s. Every time a diode switches from on to off or vice versa, the configuration of the linear network changes. Adding more detail to the ap ... more details

File Robotino robview2 sfc.png thumb Robotino View 2 Programmierumgebung main program view . Robotino is a mobile robot system for education, training and research made by Festo Didactic . Robotino is based on an omni directional drive assembly, which enables the system to roam freely. The robot is controlled by an industry standard PC system, which is powerful enough to plan routes for fully autonomous driving. Via a WLAN Link, Robotino can send all sensor readings to an external PC. In the other direction, control commands can be issued by the external PC. This way, control programs can run on the external PC or on Robotino directly. Mixed mode or shared control are also possible. For users with little prior robotics knowledge, Robotino can be readily programmed in its native programming environment RobotinoView II. More experienced programmers may find it useful that the robot can also be programmed in C programming language C , C , Java programming Java , Dotnet .NET , Matlab , Simulink , Labview and Microsoft Robotics Developer Studio . The omnidirectional drive consists of three Mecanum wheels, all of which are individually controllable. These wheels are arranged at angles of 120 . Robotino has a bumper sensor around its circumference, infrared distance sensors, a color camera with VGA resolution, optical wheel encoders, power measurement for the entire system and the various motors, as well as a battery voltage monitor. Moreover, as optional additional sensors, Robotino can be equipped with a precise Laser scanner, a gyroscope, and an indoor positioning system Northstar by evolution robotics .
