Abstract the describing function is a powerful tool for characterising nonlinear dynamical systems in the frequency domain.
Two of the most powerful (and common) ways to represent systems are the transfer function form and the state space form. This page describes how to transform a transfer function to a state space representation, and vice versa. Converting from state space form to a transfer function is straightforward because the transfer function form is unique.
