On Goursat Normal Forms, Prolongations, and Control Systems
نویسنده
چکیده
In this paper, the method of exterior diflerential systems for analyzing nonlinear systems is presented. Conditions are given for converting Pfafian systems into Goursat normal f o r m , and for converting control systems into Brunovsky form. All of the existing results on feedback linearization for control systems can be restated in the language of Pfafian systems, and in addition, new conditions for linearizing control systems using dynamic extension are given.

The Multi-steering N-trailer System: a Case Study of Goursat Normal Forms and Prolongations
In this paper, wheeled mobile robots towing trailers are used as examples of systems which can be converted into extended Goursat normal form. For some con gurations of this class of systems, a prolongation of the Pfa an system is necessary before the Goursat form can be achieved. The advantage of the Goursat form is that once the kinematic constraints are in this normal form, the point-to-poin...
متن کاملContact Coordinates for Partial Prolongations
Let V be a vector field distribution on manifold M . We give an efficient algorithm for the construction of local coordinates on M such that V may be locally expressed as some partial prolongation of the contact distribution C (1) q , on the 1 st order jet bundle of maps from R to R, q ≥ 1. It is proven that if V is locally equivalent to a partial prolongation of C (1) q then the explicit const...
متن کامل0 Extended Goursat Normal Forms with Applications to Nonholonomic Motion Planning
The theme of this paper is the generalization of Goursat normal forms for Pfaffian systems with co-dimension greater than two. There are necessary and sufficient conditions for the existence of coordinates that transform a Pfaffian system with co-dimension greater than two into an extended Goursat normal form, which is the dual of the multiple-chain, single-generator chained form mentioned in o...
متن کاملA Monster Tower Approach to Goursat Multi-flags
We consider the problem of classifying the orbits within a tower of fibrations with P-fibers that generalize the Monster Tower due to Montgomery and Zhitomirskii. The action on the tower is given by prolongations of diffeomorphism germs of 3-space. As a corollary we give the first steps towards the problem of classifying Goursat 2-flags of small length. In short, we classify the orbits within t...
متن کاملA Constructive Generalised Goursat Normal Form
We provide necessary and sufficient conditions on the derived type of a vector field distribution V in order that it be locally equivalent to a partial prolongation of the contact distribution C (1) q , on the 1 order jet bundle of maps from R to R, q ≥ 1. This result fully generalises the classical Goursat normal form. Our proof is constructive: it is proven that if V is locally equivalent to ...
