Abstract: The image-based visual control system is studied .Firstly, the Image Jacobin Matrix (IJM) for GRB-400 robot which is a dynamic look and move system has been established. Then, a hierarchical Model Reference Adaptive Control(MRAC) law combined with a fuzzy regulator is proposed to solve the control problem, and the comparison of the experimental step responses between system with fuzzy logic and system without fuzzy regulator is delivered. The experimental results show the feasibility and advantage of the control law proposed.

Key words: visual servo, robot, hierarchical MRAC, fuzzy logic
