Discrete forced Van Der Pol's system (Euler method)





This system do the illustration of the use of a single step integrator in order to solve a continuous system.
Here the system is solved with the backward Euler method. The forced Van Der Pol's oscillator is described with this system of state equation :


where parameters $ T$ is the period of the driven oscillator and $ A$ its amplitude.


Te   = 0.01
ci   = [-1;0]
A    = 0.5;
wo   = 1.1;
To   = 2*%pi/wo;
Tfin = 90
