Abstract

In this paper a novel kinematic model is proposed where the transformation between the robot posture and the system state is bijective. A nonlinear control law is constructed in the Lyapunov stability analysis framework. This control law achieves a global asymptotic stability of the system based on the usual requirements for reference velocities. The control law is extensively analysed and compared to some existing, globally stable control laws.
