VanDerPol

The model implements the Van der Pol oscillator.

der(x0) = x1
der(x1) = mu * ((1 - x0 * x0) * x1) - x0

with the variables

Variable Start Unit Causality Variability Description
time independent continuous Simulation time
x0 2 output continuous the first state
der(x0) local continuous
x1 0 output continuous the second state
der(x1) local continuous
mu 1 parameter fixed

The plot shows the trajectories of the output variables computed with fmusim.
