摘要
A new input-to-state scaling scheme is first introduced to transform a class of nonholonomic systems in a chained form with strong nonlinear drifts and unknown constant parameters into a strict feedback form. The backstepping technique is then applied to design a global adaptive stabilization controller. A switching strategy based on the control input magnitude rather than the time is derived to get around the phenomenon of uncontrollability. Simulation examples validate the effectiveness of the proposed controller. © 2002 Elsevier Science B.V. All rights reserved.
