Consider the system given by


with

so that

Now consider the definition of a new set of state variables:

In terms of the original state variables
or

We now restate the original state representation and plug this definition of q, and solve

This gives us our new state space representation


with

Details of the solution (with MatLab) are here (html, .m).
