Hybrid bond graph
Encyclopedia
A hybrid bond graph is a graphical description of a physical dynamic system
with discontinuities (i.e., a hybrid dynamical system
). Similar to
a regular bond graph
, it is an energy-based
technique. However, it allows instantaneous switching of the junction structure, which may violate the principle of continuity of power (Mosterman and Biswas, 1998).
Dynamical system
A dynamical system is a concept in mathematics where a fixed rule describes the time dependence of a point in a geometrical space. Examples include the mathematical models that describe the swinging of a clock pendulum, the flow of water in a pipe, and the number of fish each springtime in a...

A hybrid system is a dynamic system that exhibits both continuous and discrete dynamic behavior – a system that can both flow and jump...

Bond graph
A bond graph is a graphical representation of a physical dynamic system. It is similar to the better known block diagram and 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...

Energy
In physics, energy is an indirectly observed quantity. It is often understood as the ability a physical system has to do work on other physical systems...
