Abstract :
This contribution presents a numerical approach to approximate feedback linearization which transforms a single input nonlinear system into an approximately linear system. Linear matrix equations are explicitly derived for determining the nonlinear change of coordinates and the nonlinear feedback that approximately linearize the nonlinear system. If these linear matrix equations are not solvable a least square solution by applying the Moore-Penrose inverse is proposed. The results of the paper are illustrated by the approximate feedback linearization of an inverted pendulum on a cart
