20-sim
20-sim is commercial modeling and simulation program for multi-domain dynamic systems, which is developed by Controllab. With 20-sim, models can be entered as equations, block diagrams, bond graphs and physical components. 20-sim is widely used for modeling complex multi-domain systems and for the development of control systems. Use 20-sim supports four methods for modeling dynamic systems: iconic diagrams, block diagrams, bond graphs and equations. All these methods are allowed to be used in one model. The package has advanced support for bond graph modeling, making it well known in bond graph communities. For modeling physical systems, the package provides libraries for electrical systems, mechanical systems, hydraulics systems and thermal systems. For block diagrams, libraries comparable to those of Simulink, are provided. A feature of the software is the option to create models with differential equations and package them as block diagram elements or physical components. ...

TUTSIM
TUTSIM was the first commercial simulation software ever to run on an IBM-PC. The package was used for the modeling and simulation of multi-domain systems using differential equations and bond graphs. History TUTSIM (Twente University of Technology SIMulator) was developed at the Control Laboratory of the University of Twente in the early-1970s. The program was initially created for the PDP-11 and LSI-11 series of DEC. At the end of the 1970s it was ported to run on microprocessors like the MOS Technology 6502 of the Apple II and the Intel 8086 of the IBM Personal Computer. The company Meerman Automation took over the development of the package in the early-1980s. The rise of the IBM PC gave TUTSIM its world fame, making scientific simulation software available for researchers all over the world. Failing to meet the demands of a graphical user interface with the rise of Microsoft Windows in the late-1980s the popularity of TUTSIM slowly faded away. Multiple requests from bond gra ...

VisSim
VisSim is a visual block diagram program for simulation of dynamical systems and model-based design of embedded systems, with its own visual language. It is developed by Visual Solutions of Westford, Massachusetts. Visual Solutions was acquired by Altair in August 2014 and its products have been rebranded as Altair Embed as a part of Altair's Model Based Development Suite. With Embed, you can develop virtual prototypes of dynamic systems. Models are built by sliding blocks into the work area and wiring them together with the mouse. Embed automatically converts the control diagrams into C-code ready to be downloaded to the target hardware. VisSim or now Altair Embed uses a graphical data flow paradigm to implement dynamic systems based on differential equations. Version 8 adds interactive UML OMG 2 compliant state chart graphs that are placed in VisSim diagrams. This allows the modeling of state based systems such as startup sequencing of process plants or serial protocol decodi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bond Graphs
A bond graph is a graphical representation of a physical dynamic system. It allows the conversion of the system into a state-space representation. It is similar to a block diagram or signal-flow graph, with the major difference that the arcs in bond graphs represent bi-directional exchange of physical energy, while those in block diagrams and signal-flow graphs represent uni-directional flow of information. Bond graphs are multi-energy domain (e.g. mechanical, electrical, hydraulic, etc.) and domain neutral. This means a bond graph can incorporate multiple domains seamlessly. The bond graph is composed of the "bonds" which link together "single-port", "double-port" and "multi-port" elements (see below for details). Each bond represents the instantaneous flow of energy (''dE''/''dt'') or power. The flow in each bond is denoted by a pair of variables called power variables, akin to conjugate variables, whose product is the instantaneous power of the bond. The power variables are ...

Simulink
Simulink is a MATLAB-based graphical programming environment for modeling, simulating and analyzing multidomain dynamical systems. Its primary interface is a graphical block diagramming tool and a customizable set of block libraries. It offers tight integration with the rest of the MATLAB environment and can either drive MATLAB or be scripted from it. Simulink is widely used in automatic control and digital signal processing for multidomain simulation and model-based design. Add-on products MathWorks and other third-party hardware and software products can be used with Simulink. For example, Stateflow extends Simulink with a design environment for developing state machines and flow charts. MathWorks claims that, coupled with another of their products, Simulink can automatically generate C source code for real-time implementation of systems.

Footnotes
A note is a string of text placed at the bottom of a page in a book or document or at the end of a chapter, volume, or the whole text. The note can provide an author's comments on the main text or citations of a reference work in support of the text. Footnotes are notes at the foot of the page while endnotes are collected under a separate heading at the end of a chapter, volume, or entire work. Unlike footnotes, endnotes have the advantage of not affecting the layout of the main text, but may cause inconvenience to readers who have to move back and forth between the main text and the endnotes. In some editions of the Bible, notes are placed in a narrow column in the middle of each page between two columns of biblical text. Numbering and symbols In English, a footnote or endnote is normally flagged by a superscripted number immediately following that portion of the text the note references, each such footnote being numbered sequentially. Occasionally, a number between brack ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simulation Language
A computer simulation language is used to describe the operation of a simulation on a computer.Fritzson, Peter, and Vadim Engelson.Modelica—A unified object-oriented language for system modeling and simulation" European Conference on Object-Oriented Programming. Springer, Berlin, Heidelberg, 1998. There are two major types of simulation: continuous and discrete event though more modern languages can handle more complex combinations. Most languages also have a graphical interface and at least a simple statistic gathering capability for the analysis of the results. An important part of discrete-event languages is the ability to generate pseudo-random numbers and variants from different probability distributions.

Twente
Twente ( nl, Twente , Tweants dialect: ''Tweante'') is a region in the eastern Netherlands. It encompasses the most urbanised and easternmost part of the province of Overijssel. Twente is most likely named after the Tuihanti or Tvihanti, a Germanic tribe that settled in the area and was mentioned by the Roman historian Tacitus. The region's borders are defined by the Overijssel region of Salland in the northwest and west (the river Regge roughly defines the western border), the German County of Bentheim in the northeast and east (the river Dinkel roughly defines the eastern border) and the Gelderland region of the Achterhoek in the south. Twente has approximately 620,000 inhabitants, most of whom live in its three largest cities: Almelo, Hengelo and Enschede, the latter being the main city of the region. It comprises fourteen municipalities: Almelo, Borne, Dinkelland, Enschede, Haaksbergen, Hellendoorn, Hengelo, Hof van Twente, Losser, Oldenzaal, Rijssen-Holten, Tubbergen, Twe ...
