Abstract :
Stability of feature-based visual servo controllers proposed so far is local. The initial features far from the reference may converge to features different from the reference or even worse they may not converge. In this paper, stability of feature-based visual servo is considered by using potential. The stable region is visualized and artificial potential switching is proposed to extend the stable region
