3.  Electro hydraulic actuators involves both electrical and
hydraulic systems.
 It includes several energy conversions
electrical Mechanical
rotation
Hydraulic Mechanical
translation
 The bond graph presents the unique feature of being able
to model systems in different energy domains using the
same approach with a single model.

5.  Deliver great power without taking up too much
space or weight.
 Can carry heavy loads.
 Operated quickly.
 Do not fail under overloading
 Good reliability

9.  Equivalent one-line bond graph
 Hydraulic parameters have the mean values of
real parameters
 Ignoring leakage coefficient, and hydraulic
pump stiffness.
 Accumulator and pressure limiters are not
represented

14.  Through the bond graph representation, heterogeneous
systems such as electro-hydraulic aeronautic actuators
can be efficiently modelled.
 Complexity of bond graph can be varied according to our
needs.
