ANY (CONTROLLABLE) DRIFTLESS SYSTEM WITH 3 INPUTS AND 5 STATES IS FLAT

摘要

A very simple classification of Pfaffian systems of dimension 2 in 5 variables is given. It is used to show that any controllable driftless system with 3 inputs and 5 states is 0-flat and can be put into multi-input chained form by dynamic feedback and coordinate change. [References: 19]
