Abstract :
The trajectory tracking control problem of uncertain dynamic nonholonomic mobile robots is addressed in this paper. A novel uncertain camera-object visual servoing kinematic tracking error model is proposed firstly. And then, based on this model, a new adaptive torque tracking controller is presented in the presence of parametric uncertainties associated with the camera system and mechanical dynamic system. The controller synthesis is based on Lyapunov´s direct method and back-stepping technique. Simulation results are provided to illustrate the performance of the control law.
