Automatic differentiation of hybrid models
Illustrated by Diffedge Graphic Methodology
Survey
This web page gives access to the computer experiment described in a companion paper. Read the paper.
Look at the maple and Matlab examples: 1.2 An illustration in Maple. Codegen package.
2.1 Introducing new functions
Diff
Differential Algebra
2.3.1 Flat systems


1.
Animation of a car based on flat parametrization.
2. Crossing an apparent
singularity by
changing the flat outputs


3.
Crossing an intrinsic singularity using power series.
4. Without power series, the position of the car at t=0.5 is still
correct, but not that of the front wheel.2.4 Loops. Solving “algebraic” equations.
Newton method
