# Bond graph

A Bond graph is a graphical representation of a physical dynamic system. [1]

## Block diagram

A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks.

## Daisy chain (electrical engineering)

In electrical and electronic engineering a daisy chain is a wiring scheme in which multiple devices are wired together in sequence or in a ring.

## Directed graph

In mathematics, and more specifically in graph theory, a directed graph (or digraph) is a graph, or set of vertices connected by edges, where the edges have a direction associated with them.

## Dynamical system

In mathematics, a dynamical system is a set of relationships among two or more measurable quantities, in which a fixed rule describes how the quantities evolve over time in response to their own values.

## Energy

In physics, energy is a property of objects which can be transferred to other objects or converted into different forms, but cannot be created or destroyed.

## Force

In physics, a force is any interaction that, when unopposed, will change the motion of an object.

## Graph (mathematics)

In mathematics, and more specifically in graph theory, a graph is a representation of a set of objects where some pairs of objects are connected by links.

## Gyrator

A gyrator is a passive, linear, lossless, two-port electrical network element proposed in 1948 by Bernard D. H. Tellegen as a hypothetical fifth linear element after the resistor, capacitor, inductor and ideal transformer.

## Henry Paynter

Henry M. Paynter IV (August 11, 1923 - June 14, 2002) is known worldwide as the inventor of bond graphs.

## Hybrid bond graph

A hybrid bond graph is a graphical description of a physical dynamic system with discontinuities (i.e., a hybrid dynamical system).

## Kirchhoff's circuit laws

Kirchhoff's circuit laws are two equalities that deal with the current and potential difference (commonly known as voltage) in the lumped element model of electrical circuits.

## Lever

A lever is a machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum.

## LMS Imagine.Lab Amesim

LMS Imagine.Lab Amesim is a commercial simulation software for the modeling and analysis of multi-domain systems.

## Massachusetts Institute of Technology

The Massachusetts Institute of Technology (MIT) is a private research university in Cambridge, Massachusetts.

## Power (physics)

In physics, power is the rate of doing work.

## RC circuit

A resistor–capacitor circuit (RC circuit), or RC filter or RC network, is an electric circuit composed of resistors and capacitors driven by a voltage or current source.

## Signal-flow graph

A signal-flow graph or signal-flowgraph (SFG), invented by Shannon, but often called a Mason graph after Samuel Jefferson Mason who coined the term, is a specialized flow graph, a directed graph in which nodes represent system variables, and branches (edges, arcs, or arrows) represent functional connections between pairs of nodes.

## State-space representation

In control engineering, a state-space representation is a mathematical model of a physical system as a set of input, output and state variables related by first-order differential equations.

## Transformer

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

## University of Twente

University of Twente (Dutch: Universiteit Twente) is a university located in Enschede, Netherlands.

## 20-sim

20-sim is commercial modeling and simulation program for multidomain dynamic systems, which is developed by Controllab.
