Adaptive Stabilization of Nonholonomic Mobile Robots with Unknown Kinematic Parameters
Authors: ,
Abstract: This paper investigates the problem of adaptive stabilization of nonholonomic mobile robots with nonholonomic constraints under the condition that the kinematic parameters are unknown and no known constants can (lower and upper) bound them. By defining a new unknown parameter which need dynamic updating, and also by using input-state-scaling transformation and backstepping technique, an adaptive state-feedback stabilizing controller is designed. The asymptotical stability of the control system is proved with Lyapunov stability theory. A simulation example is provided to show the effectiveness of the proposed method.
