Simscape Language: Van Der Pol’s Equation

Simscape language example showing how to implement and solve a nonlinear second-order ODE.

This file contains the Simscape language source code implementing Van Der Pol’s equation (x′′ - μ(1-x2)x′ + x = 0). We rewrite the equation as a system of first-order ordinary differential equations (ODE), and then implement them as a vector. This file also contains a Simulink model that can be used to plot the solution to this equation in time.
