In this paper the authors address the tracking problem for a class of nonho
lonomic chained form control systems. A recursive technique is proposed whi
ch appears to be an extension of the currently popular integrator backstepp
ing idea to the tracking of nonholonomic control systems. Conditions are gi
ven under which the problems of semiglobal tracking and global path-followi
ng are solved for a nonholonomic system in chained form and its dynamic ext
ension. Results on local exponential tracking are also obtained. Two physic
al examples of an articulated vehicle and a knife edge are provided to demo
nstrate the effectiveness of our algorithm through simulations.
